java.lang.RuntimeException: org.apache.hadoop.hbase.ZooKeeperConnectionException: HBase is able to connect to ZooKeeper but the connection closes immediately. This could be a sign that the server has too many connections (30 is the default). Consider inspecting your ZK server logs for that error and then make sure you are reusing HBaseConfiguration as often as you can. See HTable's javadoc for more information.

解決方法禁用IPV6，將/etc/hosts檔案里面的：：1 localhost那一行刪掉重啟
[grid@rac1 ~]$ cat /etc/hosts
127.0.0.1 localhost.localdomain localhost
# ::1 localhost6.localdomain6 localhosti6
192.168.2.101 rac1.localdomain rac1
192.168.2.102 rac2.localdomain rac2
