Subject [jira] [Commented] (HBASE-15425) Failing to write bulk load event marker in the WAL is ignored
Date Thu, 10 Mar 2016 09:46:40 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15425?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15188977#comment-15188977

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

Thanks all for the comments.

I think same hfile with different seq ids will not cause any impact as in case of bulk loaded
data replication we copy these source hfiles to peer cluster and then almost run this bulk
load tool again, so it will generate a new hfile as the per seq id in peer cluster. HFiles
with different seq ids should also not impact as the data in both these hfiles are same, so
it will not create any difference.

> 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.
