> If you have quotas properly set for a given path, i.e.:
> {noformat}
> create /zookeeper/quota/test/zookeeper_limits 'count=1,bytes=100'
> create /zookeeper/quota/test/zookeeper_stats 'count=1,bytes=100'
> {noformat}
> and then you update the limits znode with bogus data, i.e.:
> {noformat}
> set /zookeeper/quota/test/zookeeper_limits ''
> {noformat}
> you'll crash the cluster because IllegalArgumentException isn't handled when
> dealing with quotas znodes:
> https://github.com/apache/zookeeper/blob/ZOOKEEPER-823/src/java/main/org/apache/zookeeper/server/DataTree.java#L379
> https://github.com/apache/zookeeper/blob/ZOOKEEPER-823/src/java/main/org/apache/zookeeper/server/DataTree.java#L425
> We should handle IllegalArgumentException. Optionally, we should also throw
> BadArgumentsException from PrepRequestProcessor.
