Akira AJISAKA updated AMBARI-15588:
-----------------------------------
Description:
If we want to rotate ambari-metrics-monitor.out by logrotate (using
copytruncate option), we need to use ">>" instead of ">" not to keep the file
offset to write. If the offset is kept, null characters are padded in the new
file.

nohup ${PYTHON} ${METRIC_MONITOR_PY_SCRIPT} "$@" > ${OUTFILE} 2>&1 &

nohup ${PYTHON} ${METRIC_MONITOR_PY_SCRIPT} "$@" >> ${OUTFILE} 2>&1 &
