> Whenever the balancer starts, it will redirect the sys out to the out log
> file. And balancer writes the system output to the log file, at the same
> time script also will try to append ulimit output.
> {noformat}
> # capture the ulimit output
> if [ "true" = "$starting_secure_dn" ]; then
> echo "ulimit -a for secure datanode user $HADOOP_SECURE_DN_USER" >> $log
> # capture the ulimit info for the appropriate user
> su --shell=/bin/bash $HADOOP_SECURE_DN_USER -c 'ulimit -a' >> $log 2>&1
> elif [ "true" = "$starting_privileged_nfs" ]; then
> echo "ulimit -a for privileged nfs user $HADOOP_PRIVILEGED_NFS_USER"
> >> $log
> su --shell=/bin/bash $HADOOP_PRIVILEGED_NFS_USER -c 'ulimit -a' >>
> $log 2>&1
> else
> echo "ulimit -a for user $USER" >> $log
> ulimit -a >> $log 2>&1
> fi
> sleep 3;
> if ! ps -p $! > /dev/null ; then
> exit 1
> fi
> {noformat}
> But the problem is first few lines of ulimit is overridding by the log of
> balancer.
