decrease log verbosity of container log output ?

[#1]

Hi,

I am facing lots of "bad dir status" issues on Nodemanagers while running huge job. This is caused by flooding the container log files with [DEBUG] messages (in detail the 'syslog' file is getting very large).

How can I modify the loglevel of the container specific log to reduce the size of the syslog file ?

E.g.:

$ ls -alh 
./container_e12_1453036276967_0004_01_000004:
total 7.4G
drwxr-s---  2 siad hadoop 4.0K Jan 17 18:39 .
drwxr-s--- 10 siad hadoop 4.0K Jan 17 20:21 ..
-rw-r-----  1 siad hadoop  222 Jan 17 18:47 stderr
-rw-r-----  1 siad hadoop    0 Jan 17 18:39 stdout
-rw-r-----  1 siad hadoop 7.4G Jan 17 18:47 syslog

In /etc/hadoop I cannot find any config setting including the value 'debug', so where does this DEBUG output come from ?

Thanks, Gerd
