Konstantin Boudnik commented on MAPREDUCE-1753:
-----------------------------------------------
It isn't about my satisfaction. It's two bits return value which is done as
boolean type. C language doesn't have it that's why they use integer instead.
Now, about suspend resume process: you are right, it is generic. Which
technically allow to suspend a daemon VM's process and never be able to resume
it. But It seems to be Ok, I guess. I was totally confused by the fact that
this has been tracked by a MAPREDUCE JIRA :( I'm moving this ticket out to
HADOOP.
