Vinod K V commented on MAPREDUCE-1318:
--------------------------------------
Thanks for taking this up, Anatoli. I've got some comments:
- Some of the exit codes are specific to commands other than launchTaskJVM()
and runDebugScrip() and some are even common to multiple other commands.
Ideally we should separate exit codes per command, but because there are many
common codes too, I am for documenting everything in the class's javadoc
instead of doing it per command.
- We should also document these codes in the forrest documentation
(src/docs/src/documentation/content/xdocs/cluster_setup.xml LinuxTaskController
section)
