Unable to Restart running Zookeeper instance

[Nitin Arora]

Hi All,

I have setup exhibitor using the standalone jar generated using the latest pom file version 1.5.2. I'm using shared configuration and S3 is the configuration location. Exhibitor detects the running zookeeper instance but when I try to restart the zookeeper instance from the Control Panel I get the following exception.

INFO  com.netflix.exhibitor.core.activity.ActivityLog  Attempting to stop instance [ActivityQueue-0]

INFO  com.netflix.exhibitor.core.activity.ActivityLog  Attempting to start/restart ZooKeeper [ActivityQueue-0]

ERROR com.netflix.exhibitor.core.activity.ActivityLog  Trying to kill running instance [ActivityQueue-0]

Can somebody help?

Thanks

Sounds like the directory you’ve specified for the ZooKeeper install is not correct. The error message should be better of course.

Hi JZ,

Thanks for the reply. It was indeed the path of the zookeeper installation directory. I was using the $HOME environment variable in my path of the zookeeper installation but it does not work. 

When I specified the full absolute path of the zookeeper directory. It did work.
