Daryn Sharp updated HADOOP-7853:
--------------------------------
Attachment: HADOOP-7853-1.patch
Per Jitendra's comments:
# Added {{isLogDebugEnabled}}
# Fixed
# I reverted 2 of the log lines. They made it easier to eyeball a noisy log
but aren't strictly needed. I left the one line that dumps the subject when no
TGT is found. The reason is this line is what finally led us to the problem
when we saw that the subject contained only unix credentials.
> multiple javax security configurations cause conflicts
