Hari Sekhon commented on MAPREDUCE-6401:
----------------------------------------
Yes the attached log is from the container task logs obtained via the RM.
I would have expected a failing shell call should print the command, status
code and both stderr and stdout with which to debug/reproduce. It's clear
something is different since these are new nodes in the cluster that are giving
these problems but it's not clear what is wrong because the debug output is so
vague - I'm trying to fix it blindfolded.
