hbase常见问题

1、初始化连接错误

2016-03-23 17:54:26,233 ERROR [org.apache.hadoop.hbase.client.HConnectionManager] - <Connection not found in the list, can't delete it (connection key=HConnectionKey{properties={hbase.rpc.timeout=60000, hbase.zookeeper.property.clientPort=2181, hbase.client.pause=100, zookeeper.znode.parent=/hbase, hbase.client.retries.number=35, hbase.zookeeper.quorum=localhost}, username='luoyq'}). May be the key was modified?>

　　解决：setting delete-connection to false, (default is 'true')

<hdp:hbase-configuration configuration-ref="hadoopConfiguration" delete-connection="false" zk-quorum="${hbase.zk.host}" zk-port="${hbase.zk.port}"/>
