Hemanth Yamijala commented on HADOOP-2961:
------------------------------------------
New patch handles the hostname and port related problems well.
However, there are two issues with the patch for the ringmaster:
- Consider a scenario where gridservice-hdfs is external. If the ringmaster
node does not contain a valid pkgs option in the gridservice-hdfs section and
no tarball is used, the current code will fail. It need not. Because the
ringmaster code never uses the gridservice-hdfs.pkgs option. It only uses the
gridservice-mapred.pkgs option. This is what was intended in HADOOP-2946.
- If tarball is not specified and gridservice-mapred has an invalid location,
the failure is not recorded in the log file. This is a regression.
Other than above two, I think the rest is fine.
> [HOD] Hod expects port info though external host is not mentioned.
