Rodrigo Schmidt commented on MAPREDUCE-1512:
--------------------------------------------
This patch is mostly refactoring the code. It simplifies some things, and
optimizes others. I don't think we need new tests since there is no bug or new
feature associated with it.
> RAID could use HarFileSystem directly instead of FileSystem.get

> Key: MAPREDUCE-1512
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1512
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: contrib/raid
> Reporter: Rodrigo Schmidt
> Assignee: Rodrigo Schmidt
> Priority: Minor
> Attachments: MAPREDUCE-1512.1.patch, MAPREDUCE-1512.patch
>
>
> Makes the code run slightly faster and avoids possible problems in matching
> the right filesystem like the stale cache reported in HADOOP-6097.
> This is a minor improvement for trunk, but it is really helpful for people
> running RAID on earlier releases susceptible to HADOOP-6097, since RAID would
> crash on them.
