HBase启动过后几个小时后挂掉

HBase启动过后几个小时后有些节点挂掉

查看HBase日志信息如下：

2015-07-08 17:23:05,604 ERROR [RS_OPEN_REGION-datanode07:60020-1] handler.OpenRegionHandler: Failed open of region=grid_observe_1x1,+072.270_+028.110_0000_20150611200000_0000_00,1434307000932.4ecbbfe8c7991

后来发现HBase上的数据表有丢失，而在Zoookeeper上依旧存在此数据表信息，

解决方案：

将Zookeeper数据表中的信息删除，之后再HBase数据中重新建立此数据表，之后重启HBase数据库。
