Subject [jira] [Commented] (MAPREDUCE-5699) Tagging support for MR jobs
Date Wed, 05 Feb 2014 23:30:09 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13892751#comment-13892751

Karthik Kambatla commented on MAPREDUCE-5699:
---------------------------------------------

bq. should we make the running MRAppMaster/Job remember the tags as well. One of reason is
that we need to parse them to JHS as the requirement of MAPREDUCE-5658.
The jobconf should have mapreduce.job.tags - the JHS should be able read it from jobconf.

bq. Another thing I'm considering is whether we'd like to support more features that are made
possible by tags. For example, JobClient can also filter applications by tags. Thoughts?
It is a good idea to support in JobClient. I can add an API to JobClient to look for active/running
MR jobs with a particular tag. For finished jobs, we should probably do it after JHS-related
changes?

> YARN-1399 / YARN-1461 add support for tagging YARN applications. MR should expose to
users, so they can set tags on an MR job.
