-Re: Manage Kafka using supervisor, failed to restart
David DeMaagd 2012-10-22, 17:25
Yes, that is likely the case - if the kafka-server-start.sh you're using
is the 'out of the box' version, then you're getting a shell running the
java process, and supervisor is likely only seeing the shell. One way
to work around this is to change the last line to be:
exec $(dirname $0)/kafka-run-class.sh kafka.Kafka $@
At which the shell process will be replaced with the java process, so
signals from supervisor will end up going direct to the java proc.
What you may end up with at that point is trying to restart too fast -
kafka can take a little bit (generally not more than a few seconds)
depending on the workload it is under at the time.
