Nicklee007 opened a new pull request #14701:
URL: https://github.com/apache/pulsar/pull/14701
Master Issue: #14700
### Motivation
Fix the failed pid occupied check. we'll fail when use pulsar-daemon start
or stop process, after the last time we exit the process direct kill or the
progress occurred non-normal exit, then the bin/pulsar-broker.pid are retained,
and the pid in the file is occupied by the thread in other progress.
### Modifications
Change the pid occupied check from 'kill -0 $pid' to 'ps -p $pid'. The both
will return false when the pid is occupied by one progress, but 'kill -0 $pid'
will return true when the pid is occupied by one progress's sub thread.
