Checksums and signatures were OK.
I also ran an API compatibility check
(https://issues.apache.org/jira/browse/HADOOP-7035,
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
org.apache.hadoop.io.Writable
org.apache.hadoop.mapred.JobClient.getQueueAclsForCurrentUser()
Class org.apache.hadoop.mapred.TaskTracker$LocalStorage
"E1.2 - API type removed" : CLASS public static
org.apache.hadoop.mapred.TaskTracker$LocalStorage
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
(http://stackoverflow.com/questions/3524150/is-it-possible-to-disable-javacs-inlining-of-static-final-variables).
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.
Cheers,
Tom
