HBase 报错系列之region is not online

报错信息：

ERROR org.apache.hadoop.hbase.regionserver.HRegionServer: Received CLOSE for a region which is not online, and we're not opening.

2016-12-07 16:00:42,558 INFO org.apache.hadoop.hbase.regionserver.RSRpcServices: Close dc4a28b161ff37666cc738aa5c9921bb, moving to null

2016-12-07 16:00:42,558 ERROR org.apache.hadoop.hbase.regionserver.HRegionServer: Received CLOSE for a region which is not online, and we're not opening.

原因：

当Hbase运行时候，region达到了设置的文件大小后，就要开始分裂了。分裂的过程是：

1）老region开始下线 ，这里就对应了报错日志中的is not online

2）老region分裂

3）老region关闭，这里就对应了报错日志中的 is closing

解决办法：关闭自动分裂，人为的进行分裂。

或者将单个region文件值设置大写
