Subject [jira] [Commented] (HBASE-16812) Clean up the locks in MOB
Date Thu, 26 Jan 2017 04:39:26 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16812?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15839170#comment-15839170

Jingcheng Du commented on HBASE-16812:

Thanks [~yuzhihong@gmail.com] for the quick response.
Currently the MOB_REF_TAG is only used for Put cell.
I plan to use it in the Delete cell to mark this cell has a related Delete cell in MOB del
The difference between the ref Put cell and ref Delete cell is Delete cell doesn't have a
value whereas the Put has a value which is actually the MOB file path.
