> Key: HADOOP-6695
> 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.
