Subject [jira] Updated: (MAPREDUCE-1318) Document exit codes and their meanings used by linux task controller
Date Thu, 28 Jan 2010 13:57:34 GMT

]

Vinod K V updated MAPREDUCE-1318:
---------------------------------

    Status: Open  (was: Patch Available)

Am extremely sorry Anatoli, though this one was on my list, I just couldn't arrive at this
one at all, apologies.

Looked at your patch. Trunk has already deviated much w.r.t these exit codes, let's generate
a patch only for 21 here.
 - Exit code 22 isn't defined in branch-0.21, can be removed.
 - Bigger issue - the newly added text in the forrest documentation isn't formatted at all,
so it looks bad when I generate the docs. The exit codes should be put in a table I think.
Also, it would be good if the exit codes table is moved to the "Using the LinuxTaskController"
section, towards the end of it, just before the beginning of the next section. The statement
_"The task exit codes are assigned as follows"_ here also can be modified, for the sake of
clarity to _"The exit codes for the tasks when LinuxTaskController is configured are as follows"_.
(Note: Before uploading the patch, to see how the docs looks like once they are generated
you can do "ant docs -Djava5.home=<java5.home> -Dforrest.home=<apache-forrest.home>,
or better change directory to src/documentation and run "<apache-forrest.home>/bin/forrest
run" and head to "http://localhost:8888/cluster_setup.html" in your browser.)

Cancelling the patch to include these changes.

These should be documented.
