Subject [jira] [Commented] (HBASE-16812) Clean up the locks in MOB
Date Fri, 27 Jan 2017 04:26:24 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16812?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15840940#comment-15840940

Jingcheng Du commented on HBASE-16812:

Thanks a lot [~saint.ack@gmail.com]!
bq. Do you want to write the Cell with the tag to the delFile? Or maybe it doesn't matter?
You are right, it doesn't matter. I prefer to use a cell without the tag to the del file.
bq. Is this change right?
I think it is right. If we have a {{request.isAllFiles()}}, we should drop the delete markers
{{ScanType.COMPACT_DROP_DELETES}}, otherwise retain them {{ScanType.COMPACT_RETAIN_DELETES}}.
