[jira] [Created] (BIGTOP-691) flume gets killed too fast when the
service is asked to stop
Roman Shaposhnik created BIGTOP-691:
---------------------------------------
Summary: flume gets killed too fast when the service is asked to stop
Key: BIGTOP-691
URL: https://issues.apache.org/jira/browse/BIGTOP-691
Project: Bigtop
Issue Type: Bug
Components: Init scripts
Affects Versions: 0.4.0
Reporter: Roman Shaposhnik
Assignee: Roman Shaposhnik
Fix For: 0.5.0
The flume stop script does the following:
kill -TERM ${FLUME_PID} &>/dev/null
sleep 5
kill -KILL ${FLUME_PID} &>/dev/null
It is not recommended to kill -9 flume while it is shutting down.
The correct approach is to poll to see if the pid is up every second or so, after sending the intitial TERM signal, then after some long period of time (60 seconds) if the pid is still alive then kill -9 would be appropriate.
