Siddharth Seth commented on MAPREDUCE-4306:
-------------------------------------------
The "-user" option in general seems to be broken. Even after this patch, the AM
will be localized as the original user - since the RM picks up the username
from ugi.
Maybe we should remove the "-user" option completely? and use
ApplicationConstants.Environment.USER in the AM - which is anyway set by the
RM, based on the logged in user.
