Tsz Wo (Nicholas), SZE commented on HADOOP-8323:
------------------------------------------------
Why reverting HADOOP-7940 is not done by the svn revert command but a separated
patch?
> Revert HADOOP-7940 and improve javadocs and test for Text.clear()

> 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.
