Hi Anchal,
> Thanks for your reply.I have attached the trace log.Please have a look.
Thank you. Looking at your trace:
> + '[' 0 -eq 0 ']'
> + case "$OSTYPE" in
> + /bin/echo -n 5832806
> + '[' 0 -eq 0 ']'
> + sleep 1
> ++ cat /tmp/anchalivt/zookeeper/zookeeper_server.pid
> + pid='-n 5832806'
> + ps -p '-n 5832806'
> + echo FAILED TO START
> FAILED TO START
> + exit 1
The issue is that on AIX, 'echo -n 5832806' prints '-n 5832806', instead
of handling '-n' as a flag as it does on GNU/Linux. The result is later
passed to 'ps', which cannot parse '-n 5832806' as a valid PID.
Could you try again after replacing the following line in
'bin/zkServer.sh'?
echo -n $! > "$ZOOPIDFILE"
with:
printf '%s' "$!" > "$ZOOPIDFILE"
Note that the JVMs created by your previous attempts may still be
around; you may want to kill these processes first.
HTH, -D
P.-S. — In any case, would you mind opening a ticket?
