Subject Re: [VOTE] Release Candidate 2

Checksums and signatures were OK.

I also ran an API compatibility check
https://github.com/tomwhite/hadoop-compatibility-tools) and it passed.
There were three errors, all false positives:

Class org.apache.hadoop.fs.HarFileSystem
  "E1.2 - API type removed" : field public final static int
org.apache.hadoop.fs.HarFileSystem.VERSION = 1

Class org.apache.hadoop.mapred.JobClient
  "E1.2 - API type removed" : method public

Class org.apache.hadoop.mapred.TaskTracker$LocalStorage
  "E1.2 - API type removed" : CLASS public static

In the first, the value changed from 1 to 3, which is a problem for
clients that reference these constants. We recommend that users
recompile their code, so this is not a problem. Still, we could
improve this situation in future

The second is is because getQueueAclsForCurrentUser returns a
QueueAclsInfo (a Writable) which was made public in 205.

The third is for a private inner class.
