Subject [jira] [Commented] (HBASE-15425) Failing to write bulk load event marker in the WAL is ignored
Date Wed, 09 Mar 2016 06:55:40 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15425?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15186631#comment-15186631

Ashish Singhi commented on HBASE-15425:
---------------------------------------

bq. What is the specific reason for the WAL markers to be igonored? 
I think it is a bug. We should fix it.

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?
{quote}
I need to check code fully before I comment anything about them. But these can be done later
also I think, not as part of this jira.

> 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.
