Arg, I'm used to seeing the username first... same issue though 4190
instead of 501...
You can follow along on our dev list for full details on the 3.3.0
release. It's still slated for 3/10 (tomorrow). There are some open
issues but those are non-blockers. We're having trouble with hudson
which is slowing us down. We are def. in the endgame for 3.3.0 and I'm
pushing everyone to close it out.

501 is userid, not pid.
The old pid file was deleted after the unsuccessful kill attempt. Maybe
we should keep the pid file if we are unable to kill.
Alternatively, we can use ps command to find
org.apache.zookeeper.server.quorum.QuorumPeerMain instance.
We use Tanuki wrapper around zk.
zookeeper is started automatically after reboot last night.
See /etc/rc3.d/S20zk-wrapper.sh in attachment
I will report the issue if it happens again.
BTW
There are several unresolved issues for zk 3.3.0
When can we expect zk 3.3.0 to be released ?
Thanks

That does seem unusual. Notice the pid of the current jvm is 501,
while the killed jvm is 6826. Is this 501 jvm created before 6826 or
has the pid "rolled over". Hard for me to tell... Are you running
the std zkServer.sh unmodified?
A shot in the dark: Permission issue? (i.e. zkStart failed to
overwrite an old/existing pid file due to file permissions). Perhaps
something started the server twice before stopping?
Can you reproduce this? If you do please report the issue here:

Donno if you noticed but ZK 3.3.0 (releasing this month)
changes that
message to an info. I'm hoping it reduces these types of
false positives.
:-) Not sure why we had it as warn, but that was wrong.

Hi,
I am hoping someone can help me with a zookeeper
setup. I am running
Zookeeper wih export HBASE_MANAGES_ZK=false and
start it using bin/hbase
zookeeper. It starts up fine. However when I start
up Hbase I get the
following in my log file:

I know its only a warning but I would like someone
to shed some light on
it
so I can be confident that my installation is
correct. Thank you kindly
for
your help.
Cheers
