[jira] [Commented] (HBASE-17509) Remove the mvcc preassign lock and take usage of MVCC internal lock instead

    [ https://issues.apache.org/jira/browse/HBASE-17509?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15833616#comment-15833616 ] 

Yu Li commented on HBASE-17509:
-------------------------------

Probably overlaps HBASE-17471, but it's ok to do both in parallel I guess, since HBASE-17471 is a fix of existing problem, and the JIRA here is an improvement of the mechanism.

[~allan163] and [~stack], FYI.

> This is an improvement on current mvcc preassign implementation introduced by HBASE-16698, as well as an easier way to unify the logic of put, append and increment. Thanks [~Apache9] for contributing the initial idea, will try this out in this JIRA to see how it works.
> Could also be regarded as a first try of HBASE-16873
