大叔问题定位分享（33）beeline连接presto报错

hive2.3.4

presto0.215

 

使用hive2.3.4的beeline连接presto报错

$ beeline -d com.facebook.presto.jdbc.PrestoDriver -u "jdbc:presto://localhost:8080/hive"
Error: Unrecognized connection property 'url' (state=,code=0)

增加--verbose查看详细报错

$ beeline -d com.facebook.presto.jdbc.PrestoDriver -u "jdbc:presto://localhost:8080/hive" --verbose 
Error: Unrecognized connection property 'url' (state=,code=0)

这里是connect过程报错，connect参数为

Usage: connect <url> <username> <password> [driver]

 

跟进hive和presto代码

 

org.apache.hive.beeline.BeeLine

  boolean dispatch(String line) {
...
    if (isBeeLine) {
      if (line.startsWith(COMMAND_PREFIX)) {
        // handle SQLLine command in beeline which starts with ! and does not end with ;
        return execCommandWithPrefix(line);
      } else {
        return commands.sql(line, getOpts().getEntireLineAsCommand());
      }
    } else {
      return commands.sql(line, getOpts().getEntireLineAsCommand());
    }

beeline中的命令和sql都会经过dispatch，命令执行的是execCommandWithPrefix，然后会反射调用Commands

 

org.apache.hive.beeline.Commands

  public boolean connect(String line) throws Exception {
    String example = "Usage: connect <url> <username> <password> [driver]"
        + BeeLine.getSeparator();

    String[] parts = beeLine.split(line);
    if (parts == null) {
      return false;
    }

    if (parts.length < 2) {
      return beeLine.error(example);
    }

    String url = parts.length < 2 ? null : parts[1];
    String user = parts.length < 3 ? null : parts[2];
    String pass = parts.length < 4 ? null : parts[3];
    String driver = parts.length < 5 ? null : parts[4];

    Properties props = new Properties();
    if (url != null) {
      String saveUrl = getUrlToUse(url);

    }

    String value = null;
    if (driver != null) {
      props.setProperty(JdbcConnectionParams.PROPERTY_DRIVER, driver);
    } else {
      value = Utils.parsePropertyFromUrl(url, JdbcConnectionParams.PROPERTY_DRIVER);
      if (value != null) {
        props.setProperty(JdbcConnectionParams.PROPERTY_DRIVER, value);
      }
    }

    if (user != null) {
      props.setProperty(JdbcConnectionParams.AUTH_USER, user);
    } else {
      value = Utils.parsePropertyFromUrl(url, JdbcConnectionParams.AUTH_USER);
      if (value != null) {
        props.setProperty(JdbcConnectionParams.AUTH_USER, value);

    }

    if (pass != null) {

    } else {
      value = Utils.parsePropertyFromUrl(url, JdbcConnectionParams.AUTH_PASSWD);
      if (value != null) {
        props.setProperty(JdbcConnectionParams.AUTH_PASSWD, value);
      }
    }

    value = Utils.parsePropertyFromUrl(url, JdbcConnectionParams.AUTH_TYPE);
    if (value != null) {
      props.setProperty(JdbcConnectionParams.AUTH_TYPE, value);
    }
    return connect(props);
  }

  public boolean connect(Properties props) throws IOException {
    String url = getProperty(props, new String[] {
        JdbcConnectionParams.PROPERTY_URL,
        "javax.jdo.option.ConnectionURL",
        "ConnectionURL",
    });
    String driver = getProperty(props, new String[] {
        JdbcConnectionParams.PROPERTY_DRIVER,
        "javax.jdo.option.ConnectionDriverName",
        "ConnectionDriverName",

    String username = getProperty(props, new String[] {

    });

    if (url == null || url.length() == 0) {
      return beeLine.error("Property \"url\" is required");
    }
    if (driver == null || driver.length() == 0) {
      if (!beeLine.scanForDriver(url)) {
        return beeLine.error(beeLine.loc("no-driver", url));
      }
    }

    String auth = getProperty(props, new String[] {JdbcConnectionParams.AUTH_TYPE});
    if (auth == null) {
      auth = beeLine.getOpts().getAuthType();
      if (auth != null) {
        props.setProperty(JdbcConnectionParams.AUTH_TYPE, auth);
      }
    }

    beeLine.info("Connecting to " + url);
    if (Utils.parsePropertyFromUrl(url, JdbcConnectionParams.AUTH_PRINCIPAL) == null) {
      String urlForPrompt = url.substring(0, url.contains(";") ? url.indexOf(';') : url.length());
      if (username == null) {
        username = beeLine.getConsoleReader().readLine("Enter username for " + urlForPrompt + ": ");
      }
      props.setProperty(JdbcConnectionParams.AUTH_USER, username);
      if (password == null) {
        password = beeLine.getConsoleReader().readLine("Enter password for " + urlForPrompt + ": ",
          new Character('*'));
      }
      props.setProperty(JdbcConnectionParams.AUTH_PASSWD, password);
    }

    try {
      beeLine.getDatabaseConnections().setConnection(
          new DatabaseConnection(beeLine, driver, url, props));
      beeLine.getDatabaseConnection().getConnection();

      if (!beeLine.isBeeLine()) {
        beeLine.updateOptsForCli();
      }
      beeLine.runInit();

      beeLine.setCompletions();
      beeLine.getOpts().setLastConnectedUrl(url);
      return true;
    } catch (SQLException sqle) {
      beeLine.getDatabaseConnections().remove();
      return beeLine.error(sqle);
    } catch (IOException ioe) {
      return beeLine.error(ioe);
    }
  }

注意props字段的赋值过程

 

org.apache.hive.beeline.DatabaseConnection

  public DatabaseConnection(BeeLine beeLine, String driver, String url,
       Properties info) throws SQLException {
    this.beeLine = beeLine;
    this.driver = driver;
    this.url = url;
    this.info = info;
  }

  boolean connect() throws SQLException {
...
    Map<String, String> hiveVars = beeLine.getOpts().getHiveVariables();
    if (hiveVars != null){
      for (Map.Entry<String, String> var : hiveVars.entrySet()) {
        info.put(HIVE_VAR_PREFIX + var.getKey(), var.getValue());
      }
    }

    Map<String, String> hiveConfVars = beeLine.getOpts().getHiveConfVariables();
    if (hiveConfVars != null){
      for (Map.Entry<String, String> var : hiveConfVars.entrySet()) {
        info.put(HIVE_CONF_PREFIX + var.getKey(), var.getValue());
      }
    }

    if (isDriverRegistered) {
      // if the driver registered in the driver manager, get the connection via the driver manager
      setConnection(DriverManager.getConnection(getUrl(), info));
    } else {

Commands中props赋值给DatabaseConnection的info

 

java.sql.DriverManager

    public static Connection getConnection(String url,
        java.util.Properties info) throws SQLException {

        return (getConnection(url, info, Reflection.getCallerClass()));
    }

    private static Connection getConnection(
        String url, java.util.Properties info, Class<?> caller) throws SQLException {
...
                    Connection con = aDriver.driver.connect(url, info);

DatabaseConnection的info传递给DriverManager然后传递给Driver，下面看具体的PrestoDriver

 

com.facebook.presto.jdbc.PrestoDriver

    public Connection connect(String url, Properties info)
            throws SQLException
    {
        if (!acceptsURL(url)) {
            return null;
        }

        PrestoDriverUri uri = new PrestoDriverUri(url, info);

        OkHttpClient.Builder builder = httpClient.newBuilder();
        uri.setupClient(builder);
        QueryExecutor executor = new QueryExecutor(builder.build());

        return new PrestoConnection(uri, executor);
    }

info传递给PrestoDriverUri进行初始化

 

com.facebook.presto.jdbc.PrestoDriverUri

    public PrestoDriverUri(String url, Properties driverProperties)
            throws SQLException
    {
        this(parseDriverUrl(url), driverProperties);
    }

    private PrestoDriverUri(URI uri, Properties driverProperties)
            throws SQLException
    {
        this.uri = requireNonNull(uri, "uri is null");
        address = HostAndPort.fromParts(uri.getHost(), uri.getPort());
        properties = mergeConnectionProperties(uri, driverProperties);

        validateConnectionProperties(properties);

        // enable SSL by default for standard port
        useSecureConnection = SSL.getValue(properties).orElse(uri.getPort() == 443);

        initCatalogAndSchema();
    }

    private static void validateConnectionProperties(Properties connectionProperties)
            throws SQLException
    {
        for (String propertyName : connectionProperties.stringPropertyNames()) {
            if (ConnectionProperties.forKey(propertyName) == null) {
                throw new SQLException(format("Unrecognized connection property '%s'", propertyName));
            }
        }

        for (ConnectionProperty<?> property : ConnectionProperties.allProperties()) {
            property.validate(connectionProperties);
        }
    }

所以报错“Unrecognized connection property 'url' ”意味着ConnectionProperties.forKey("url") == null

com.facebook.presto.jdbc.ConnectionProperties

ConnectionProperties中确实没有url，所以presto与hive的beeline不兼容；

尝试修改PrestoDriverUri.java，去掉校验：

 

com.facebook.presto.jdbc.PrestoDriverUri

    private static void validateConnectionProperties(Properties connectionProperties)
            throws SQLException
    {
//        for (String propertyName : connectionProperties.stringPropertyNames()) {
//            if (ConnectionProperties.forKey(propertyName) == null) {
//                throw new SQLException(format("Unrecognized connection property '%s'", propertyName));
//            }
//        }
 
        for (ConnectionProperty<?> property : ConnectionProperties.allProperties()) {
            property.validate(connectionProperties);
        }
    }

将以上几行注释

 

简单修改jar包中的class的方法，参考：https://www.cnblogs.com/barneywill/p/10552322.html

 

编译的时候发现一直报错，

presto-jdbc/com/facebook/presto/jdbc/PrestoDriverUri.java:145: error: method setupSocksProxy in class OkHttpUtil cannot be applied to given types;
            setupSocksProxy(builder, SOCKS_PROXY.getValue(properties));

  found: Builder,Optional<com.facebook.presto.jdbc.internal.guava.net.HostAndPort>

2 errors

然后发现原来是presto-jdbc打包的时候设置了relocation，会将一些包做shade并且改package，详见：

所以需要手工调整源代码中的package

okhttp3 -> com.facebook.presto.jdbc.internal.okhttp3
com.google.common -> com.facebook.presto.jdbc.internal.guava
com.facebook.presto.client -> com.facebook.presto.jdbc.internal.client

源代码地址：

https://github.com/prestodb/presto/blob/master/presto-jdbc/src/main/java/com/facebook/presto/jdbc/PrestoDriverUri.java

然后再编译就ok了，编译命令：

# javac -cp presto-jdbc-0.215.jar -d presto-jdbc presto-jdbc/com/facebook/presto/jdbc/PrestoDriverUri.java

然后重新打包，再使用beeline连接就ok了
