hbase asynchbase 异步API kerberos认证

hbase asynchbase 异步API 调用 ，如果需要kerberos认证，下面是必须的步骤，其实和opentsdb kerberos认证是一个道理。

这句很重要

KerberosClientAuthProvider   authProvider = new KerberosClientAuthProvider(hbaseClient);

，是保持 ticket 24小时刷新的。

下面是代码：

HBaseClient hbaseClient = new HBaseClient(zookeeper);

激活了kerberos需要：

 System.setProperty("java.security.auth.login.config", "D:/kbs/jaas.conf");
System.setProperty("zookeeper.sasl.client",  "false");
//下面行只在本地打开
 System.setProperty("java.security.krb5.conf",  "D:/kbs/krb5.conf");

 org.hbase.async.Config asyncConfig = new org.hbase.async.Config();
 asyncConfig.overrideConfig("hbase.zookeeper.quorum", zookeeper);
 asyncConfig.overrideConfig("hbase.security.auth.enable", "true");
 asyncConfig.overrideConfig("hbase.security.authentication", "kerberos");
 asyncConfig.overrideConfig("hbase.sasl.clientconfig", "Client");
 asyncConfig.overrideConfig("hbase.kerberos.regionserver.principal", "hbase/_HOST@HTSEC.COM");
 HBaseClient   hbaseClient = new HBaseClient(asyncConfig);
 //认证
 KerberosClientAuthProvider   authProvider = new KerberosClientAuthProvider(hbaseClient);
