Query regarding Zookeeper Windows API start/stop, using Zk as a
windows service(using prunsrv)
Hi,
I am using zookeeper in my product.
While working with zookeeper on Windows, I am creating a service(using
prunsrv) ,
I have few queries and issues. Listed them all,
Issues:
1) zkServer.cmd didn’t start on Win server 2008 machine & Win 7
Enterprise(64 bit both), had to replace the following line,
java "-Dzookeeper.log.dir=%ZOO_LOG_DIR%"
"-Dzookeeper.root.logger=%ZOO_LOG4J_PROP%" -cp "%CLASSPATH%" %ZOOMAIN%
"%ZOOCFG%" %*
to
java "-Dzookeeper.log.dir=%ZOO_LOG_DIR%"
"-Dzookeeper.root.logger=%ZOO_LOG4J_PROP%" -cp "%CLASSPATH%" %ZOOMAIN%
"%ZOOCFG%"
And it worked, could it be fixed in some other way?
2) In the zoo.cnf I specified the dataDir, still it creates some other
directory (bin/zookeeper-3.4.5zookeeper-3.4.5data/ version-2/snapshot) and
stores the snapshots there.
Queries:
1) There is no start/stop with zkServer.cmd as it is in zkServer.sh, so
basically it is started with zkServer.cmd but to stop I do a Ctrl+C/Z
So if I start the process, it is a foreground process and gets killed when I
do a ctrl+C
2) I have to create a zookeeper service, and I am using prunsrv to do that.
I figured out the following 2 ways to do so.
a) prunsrv //IS//Zookeeper --DisplayName=" ZOOKEEPER Service"
--Description=" ZOOKEEPER Service" --Startup=auto --StartMode=exe
--StartPath=%ZOOKEEPER_HOME% --StartImage=%ZOOKEEPER_HOME%\bin\zkServer.cmd
--StopTimeout=5 --LogPath=%LOGS_DIR% --LogPrefix=zookeeper --LogLevel=Info
--PidFile=zookeeper.pid --StdOutput=auto --StdError=auto
b) cd %ZOOKEEPER_HOME%\bin\
call "%~dp0zkEnv.cmd"
set ZOOMAIN=org.apache.zookeeper.server.quorum.QuorumPeerMain
prunsrv //IS//Zookeeper --DisplayName=" ZOOKEEPER Service"
--Description=" ZOOKEEPER Service" --Jvm="%JVM_DLL%"
--JvmOptions=!JAVA_OPTS!
--Environment=zookeeper.log.dir=%ZOO_LOG_DIR%;zookeeper.root.logger=%ZOO_LOG4J_PROP%;
--Startup=auto --LibraryPath=%LIB_DIR% --StartMode=jvm
--Classpath=%CLASSPATH% %ZOOMAIN% %ZOOCFG%
--StartClass=org.apache.zookeeper.server.quorum.QuorumPeerMain
--StartMethod=start --StopMode=jvm
--StopClass=org.apache.zookeeper.server.quorum.QuorumPeerMain
--StopMethod=stop --StopTimeout=10 --LogPath=%LOGS_DIR%
--LogPrefix=zookeeper --LogLevel=Info --PidFile=zookeeper.pid
--StdOutput=auto --StdError=auto
basically in the second approach I am myself doing all tasks done by the
zkServer.cmd
=>> My Query is in the second step(2b), that to stop the service there
should be a stop method exposed, so that when I stop the service it is
called.
So right now if I create a service and start it, ZK runs fine, but stopping
it takes indefinitely, so I have to go and kill the process.
Is there some stop() for the same, I see a shutdown() but there is no
description for it
I went through the class org.apache.zookeeper.server.quorum.QuorumPeerMain,
here the main() is the start method( if my understanding is correct), and
there should be some method to shutdown the process.
https://issues.apache.org/jira/browse/ZOOKEEPER-1122, exposes a start/stop,
but the stop has some issues
it throws the following error:
E:\zookeeper-3.4.5\zookeeper-3.4.5\bin>zkServer.cmd stop
"JMX enabled by default"
"Using config: E:\zookeeper-3.4.5\zookeeper-3.4.5\bin\..\conf\zoo.cfg"
"Stopping zookeeper ... "
ERROR: The process with PID 452 (child process of PID 4) could not be
terminated.
Reason: This is critical system process. Taskkill cannot end this process.
ERROR: The process with PID 4 (child process of PID 0) could not be
terminated.
Reason: Access is denied.
ERROR: The process with PID 0 (child process of PID 0) could not be
terminated.
Reason: This is critical system process. Taskkill cannot end this process.
STOPED
I am running this stop command on a Administrator console.
E:\zookeeper-3.4.5\zookeeper-3.4.5\bin>tasklist | findstr "java"
java.exe 10324 Console 1 36,036

Hi Patrick,
Thanks for the reply and encouragement.
Will fix it soon and patch against trunk
One more thing
cannot connect to http://irc.freenode.org/ so the link
http://zookeeper.apache.org/irc.html is leading the user no where.
Thanks,
Nandini

Hi Nandini, this is great feedback. It's likely that not many people
are using ZK and those cmd scripts on windows. As a result things get
stale. I'd encourage you to provide some patches agains the trunk
which incorporate your fixes. You can see more detail on how to do
that here:
