Subject [jira] [Commented] (HBASE-5418) use different memstoreTS for different operations in the same RowMutation.

    [ https://issues.apache.org/jira/browse/HBASE-5418?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13209906#comment-13209906

Phabricator commented on HBASE-5418:

tedyu has commented on the revision "HBASE-5418 [jira] use different memstoreTS for different
operations in the same RowMutation.".

  src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java:4245 Should ctr be lifted
to above the try block so that we only call mvcc.completeMemstoreInsert() for the WriteEntry's
we actually touched ?
Should we simplify beginMemstoreInsert() by letting it call this new method ?
  This would allow maintaining one method instead of two in case we add something in the future.
