[jira] [Commented] (HBASE-8253) A corrupted log blocked
ReplicationSource
[ https://issues.apache.org/jira/browse/HBASE-8253?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13648093#comment-13648093 ]
Jieshan Bean commented on HBASE-8253:
-------------------------------------
bq.how come you got this error in a normal source?
Yes, it happened in a normal source not a recovered one. Primary data node was forcely powered down, so logRoll was requested. And during that time, only partial of last edit was written. Then we saw this problem.
