>                 URL: https://issues.apache.org/jira/browse/HADOOP-6695
>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: conf
>    Affects Versions: 0.20.1
>            Reporter: Ted Yu
>
> When I tried to run HBase export in cluster mode, I copied zookeeper-3.2.1.jar to hadoop lib directory.
> But initial attempts failed with java.lang.ClassNotFoundException because job tracker wasn't restarted.
> It is desirable for job tracker to pick up new classpath without restarting which is sometimes hard to do in production environment.
