> Key: ZOOKEEPER-3766

> Project: ZooKeeper
> Issue Type: Improvement
> Components: scripts
> Affects Versions: 3.5.7
> Reporter: Christopher Tubbs
> Priority: Critical
> Labels: pull-request-available

> ZooKeeper's launch scripts use `-cp` to pass the class path to Java when
> launching. This creates insanely large command-lines which are completely
> unnecessary.
> Java respects the CLASSPATH environment variable, and this is how the class
> path should be passed to Java when the process launches.
> So, instead of doing {{java -cp $CLASSPATH ...}}, the scripts should be doing
> {{export CLASSPATH; java ...}}.
> The long command-lines make it difficult to troubleshoot, or view running
> process lists in tools like top, htop, ps, but also make it impossible to
> search and manage using tools like pgrep and pkill, which can only search for
> the first 4096 characters in the command-line. (See
> https://github.com/apache/fluo-uno/issues/243#issuecomment-601553260 for a
> specific issue involving this limit caused by ZK's scripts.)
