Harsh J updated HADOOP-8323:
----------------------------

    Attachment: HADOOP-8323.patch

Attached patch reverts HADOOP-7940, adds a note about the actual behavior of clear(), a workaround
in case freeing memory within the same object is required, and also improves test to catch
regressions of this behavior.

> 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.
