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);
