WARN  [main] zookeeper.ZKUtil: hconnection-0x33634f040x0, quorum=localhost:2181, baseZNode=/hbase Unable to set watcher on znode (/hbase/hbaseid)
org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /hbase/hbaseid

【  解决办法】

重新启动hadoop  ：start-all.sh

在接着输入：start-hbase.sh

启动hbase：hbase shell

这样就解决了。
