public static void main(String[] args) throws SQLException {
try {
Class.forName(driverName);
} catch (ClassNotFoundException e) {

e.printStackTrace();
System.exit(1);
}
ClassLoader classLoader = App.class.getClassLoader();
Enumeration<URL> paths = null;
try {
paths = classLoader.getResources("META-INF");
} catch (IOException e) {
e.printStackTrace();
} finally {
}
int count = 0;
while (paths.hasMoreElements()){
String path = paths.nextElement().toString();
if (path.indexOf("jdk") == -1){
count++;
System.out.println(path);
}
}
System.out.println(count);
//
Connection con = DriverManager.getConnection("jdbc:hive2://hdfs03.yingzi.com:2181,hdfs04.yingzi.com:2181,hdfs05.yingzi.com:2181/;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2");
Statement stmt = con.createStatement();
ResultSet res = stmt.executeQuery("show databases");
if (res.next()) {
System.out.println(res.getString(1));
}
//create table
String sql = "CREATE TABLE IF NOT EXISTS hbase_hive_table(key string, value string)\n" +
"STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'\n" +
"WITH SERDEPROPERTIES (\"hbase.columns.mapping\" = \":key,cf:json\")\n" +
"TBLPROPERTIES (\"hbase.table.name\" = \"hbase_hive_table\")";
System.out.println(sql);
stmt.execute(sql);
}
}
运行报错:
org.apache.hive.service.cli.HiveSQLException: java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/client/Connection
