hbase region 重叠问题

发现表下面有region重叠的问题，请问这个重叠问题是怎么产生的?

ERROR: (region tableName,10055595255,1444297769057.d4fa60af955ec4119f5a991fd5c3d78b.) Multiple regions have the same startkey: 10055595255

尝试下面解决办法：

1.先使用hbase hbck -fix修复
2.刷新60010页面，查看其中一个已经上线的region，将另一个region从meta表中删除

3.再次执行hbase hbck 报下面的错：
ERROR: Region hdfs://m0:9000/hbase/actionlog3_201206/3a538f83871d225fd90e610837991e2b on HDFS, but not listed in META or deployed on any region server
4.将HDFS上对应的目录删除

5.再次执行hbase hbck
