[jira] [Commented] (YARN-53) Add protocol to YARN to support GetGroups

-
Wanted to point out that the test can be simplified by using MiniYarnCluster if
the groups-tools didn't belong to RM package (which is how it should be
anyways). Will open a separate ticket for moving out tools into the client
package.

-
The update patch looks good, Bo! Particularly I like that we are not starting a
new server for looking up groups (which I somehow missed earlier). There is far
lesser code-duplication now, even without HADOOP-8805.
+1 for the patch. Tested on a single node. Committing this.

+1. Seems much simpler this way (without having to do HADOOP-8805). I'll
crosspost in HADOOP-8805 and wait for Suresh/Todd comments before committing.

Bo Wang commented on YARN-53:
-
Hi Vinod,
Thanks for looking at the patch. I'd like to clarify the two comments.
- To reflect YARN-1, do you mean move org.apache.hadoop.mapred.tools.GetGroups
to org.apache.hadoop.yarn.tools.GetGroups?
Currently there is no such package in hadoop-yarn-common yet, but I can
create one. Actually, bin/yarn rmadmin -getGroups doesn't call to
org.apache.hadoop.mapred.tools.GetGroups but
org.apache.hadoop.yarn.server.resourcemanager.tools.RMAdmin. GetGroups can be
left there for backward compatibility or removed directly.
- I am not sure what definitions in HDFS you referred to. Would you mind giving
it a bit more elaboration?
Thanks,
Bo

Yes, it's fine to port get* commands from bin/mapred to bin/yarn as they make
sense.

Hi Arun, thanks for the feedback. I have a question that currently bin/yarn
rmadmin is a set of refresh commands. Would query commands (e.g. bin/mapred
groups) also be added there?
