Subject [jira] [Updated] (YARN-1731) ResourceManager should record killed ApplicationMasters for History
Date Fri, 14 Feb 2014 02:45:22 GMT

Robert Kanter updated YARN-1731:
--------------------------------

    Attachment: YARN-1731.patch

I’ve attached a preliminary version of the patch.  Once we all agree on the specifics of
the design, I can add unit tests.  This basically writes out an empty file with the app attempt
id and user as the filename to a directory in HDFS (the JHS or something else such as the
AHS could then see it).  We can easily replace HDFS with some other FileSystem or mechanism
or make it pluggable in some fashion.

> Yarn changes required for MAPREDUCE-5641 to make the RM record when an AM is killed so
the JHS (or something else) can know about it).  See MAPREDUCE-5641 for the design I'm trying
to follow.
