Harsh J resolved HADOOP-8323.
-----------------------------
Resolution: Won't Fix
Target Version/s: (was: 3.0.0, 2.0.0)
Actually, I looked at the API and this would only impact the Text usage iff
clear() is called upon it. I do not think we should revert this. Clear must
work as intended - and clear the byte array states inside. There wouldn't be
any other way to free the memory if we didn't do this.
I do not see clear() being used in MR directly. So the largest length is still
maintained but thats not an issue (except that clear may be called for memory
gains if the user wants that).
I'm resolving this as Won't Fix (Won't revert). But if I've missed addressing
something, please reopen.

> Key: HADOOP-8323
> URL: https://issues.apache.org/jira/browse/HADOOP-8323
> Project: Hadoop Common
> Issue Type: Bug
> Components: io
> Affects Versions: 2.0.0
> Reporter: Harsh J
> Assignee: Harsh J
> Priority: Critical
>
> 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.
