Vinod Kumar Vavilapalli updated HADOOP-3464:
--------------------------------------------
Attachment: HADOOP-3464
Attaching first patch.
- This solves the problem of reporting errors on ringmaster side back to the
hod client, HodRing problems are still NOT addressed.
- Changes to hodlib/Common/setup.py are borrowed from the patch to
HADOOP-2961. Need merging of these two while committing.
- Also fixed another issue - earlier, any validation errors in ringmaster were
not getting logged due to late log initialization, changed this now so that
these errors can also be reported back to the hod client.
- Tested with 1) an invalid tar file e.g. a junk file 2) a non-existent path
value for hodring.java-home and 3) a non-existent path value for
gridservice-hdfs.pkgs and verified that errors are properly propagated back to
the hod client.
