Anoop Sam John commented on HBASE-16652:
----------------------------------------
Increment is a public exposed class and this will change the behavior of
getTimeRange API in it. Also pls see the usage of this API within our code.
See AccessController
{code}
if (checkCoveringPermission(user, OpType.INCREMENT, c.getEnvironment(),
increment.getRow(),
increment.getFamilyCellMap(), increment.getTimeRange().getMax(),
Action.WRITE)) {
{code}
This change will make NPE here.
So instead of this can be set the TimeRange to get iff Increment is having a TR
on it and it is not allTime? (See TR#isAllTime() )
> Figure out performance difference between increment and append

> When do performance test in HBASE-16625, i found it has the very big
> difference between Append and Increment (append is about 37% faster than
> increment).
> As [~stack] mentioned in
> https://issues.apache.org/jira/browse/HBASE-16610?focusedCommentId=15493166&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15493166,
> append and increment has been unified in server-side, and they looks the
> same in client-side.
> This issue is to figure out why the performance looks different between them.
