java连接docker里面的hbase

原代码

代码一直卡着报错如下：

更改代码

• hbase.zookeeper.quorum：ZooKeeper集群的地址，必须进行配置，该项默认为localhost。

• hbase.zookeeper.property.clientPort：默认为2181，可以不进行配置。

• zookeeper.znode.parent：默认为/hbase，可以不配置。

• zookeeper.session.timeout：表示RegionServer与ZooKeeper之间的会话超时时间，一旦session超时，ZooKeeper就会感知到，通知Master将对应的RegionServer移出集群，并将该RegionServer上所有Region迁移到集群中其他RegionServer
