Subject [jira] [Commented] (HBASE-17174) Use shared threadpool in BufferedMutatorImpl
Date Fri, 25 Nov 2016 06:22:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17174?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15694971#comment-15694971

ChiaPing Tsai commented on HBASE-17174:
---------------------------------------

hi [~jinghe], [~anoop.hbase]
I refactor/cleanup the code because there are too many undefined value, non-final, and unsuitable
modifiers in the HTable and BufferedMutatorImpl.
If the refactoring/cleanup is unsuitable here, i will submit a patch which only includes the
changes for threadpool.
Thanks for your comment.

> A update-heavy application, for example, loader, creates many BufferedMutator for batch
updates. But these BufferedMutators can’t share a large threadpool because the shutdown()
method will be called when closing any BufferedMutator. This patch adds a flag into BufferedMutatorParams
for preventing calling the shutdown() method in BufferedMutatorImpl#close
