> Resolved path for jstack command on supervisor is
> /home/y/share/yjava_jdk/java/jstack which doesn't exist. command returns 127
> as exit code. When a request for jstack dump is made from UI, a zookeeper
> node is created. Now supervisor keeps on reading this node, executes jstack
> command and since exit code is non-zero, doesn't delete the node afterwards.
> Thus supervisor keeps on executing the command forever and each invocation
> creates an new empty file.
