[jira] [Updated] (AMBARI-15588) Use ">>" instead of ">" to write
ambari-metrics-monitor.out
[ https://issues.apache.org/jira/browse/AMBARI-15588?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.
{code:title=ambari-metrics-monitor}
nohup ${PYTHON} ${METRIC_MONITOR_PY_SCRIPT} "$@" > ${OUTFILE} 2>&1 &
{code}
should be
{code}
nohup ${PYTHON} ${METRIC_MONITOR_PY_SCRIPT} "$@" >> ${OUTFILE} 2>&1 &
{code}
was:
