Subject [jira] [Commented] (HBASE-16812) Clean up the locks in MOB
Date Thu, 26 Jan 2017 03:53:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16812?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15839141#comment-15839141

Jingcheng Du commented on HBASE-16812:

Thanks [~huaxiang].
A pre-check (check if the current partition is expired) is added before the compaction on
a partition.
If a compaction is in progress when the cleaner cleans expired mob files, I think it is okay
to allow that partition to fail in FNFE and compaction on that partition is not necessary
anymore. The only impact is the whole compaction is failed but all the other partitions can
run successfully. How do you think on this? Thanks!
