Balancer can move this replica region to a > new region server. During the region open, replica region does not check if > primary region has been removed and moves forward. During store open, it will > recreates primary region directory at hdfs and caused inconsistency. > > In hbase-2, things get much better. To prevent the above inconsistency from > happening, it adds more checks for a replica region, i.e, if primary regions' > directory exists and there is a .regioninfo under. -- This message was sent by Atlassian Jira (v8.3.4#803005)
