Subject [jira] [Commented] (HADOOP-8323) Revert HADOOP-7940 and improve javadocs and test for Text.clear()
Date Mon, 30 Apr 2012 18:29:50 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8323?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13265086#comment-13265086
] 

Harsh J commented on HADOOP-8323:
---------------------------------

I'm unsure if I can revert a single commit back in history out. Is that possible to do Nicholas?

I can as well do a svn revert, and then add in javadocs+freshtests via this JIRA. Would that
be the right thing?

> Per [~jdonofrio]'s comments on HADOOP-7940, we should revert it as it has caused a performance
regression (for scenarios where Text is reused, popular in MR).
> The clear() works as intended, as the API also offers a current length API.
