Subject [jira] [Commented] (HBASE-15425) Failing to write bulk load event marker in the WAL is ignored
Date Wed, 09 Mar 2016 04:28:40 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15425?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15186483#comment-15186483
] 

ramkrishna.s.vasudevan commented on HBASE-15425:
------------------------------------------------

What is the specific reason for the WAL markers to be igonored?  Suppose a region open marker
is ignored due to exception what happens on Log replay?
How is the flush marker getting reused from the WAL? I have not seen this code fully to know
the full behaviour.

> During LoadIncrementalHFiles process if we fail to write the bulk load event marker in
the WAL, it is ignored. So this will lead to data mismatch issue in source and peer cluster
in case of bulk loaded data replication scenario.
