> Project: Kylin
> Issue Type: Improvement
> Reporter: liyang
> Assignee: liyang
> Fix For: v2.1.0
>
>
> The current {{DistributedLock}} could use some improvement:
> - A {{lockClient}} is unnecessarily required.
> - The {{watchPath}} is actually an on-unlock listener and the current name
> failed to make it clear.
> - Could add a blocking version of {{lockPath}} and that will ease use cases
> like KYLIN-2557 and {{GlobalDictionaryBuilder.lock()}}
> - Should add more javadoc on the interface
