-----------------------------

> Key: KYLIN-4039
> URL: https://issues.apache.org/jira/browse/KYLIN-4039
> Project: Kylin
> Issue Type: Bug
> Reporter: PENG Zhengshuai
> Assignee: PENG Zhengshuai
> Priority: Major
> Fix For: v3.0.0-alpha2
>
>
> ZookeeperDistributedLock may hold the lock and not release it when the unlock
> operation was interrupted.
> Because the unlock operation contains two steps:
> 1. peekLock: get the owner of the lock
> 2. purgeLock: purge the lock if the owner of the lock is the current client.
> If the peekLock step is interrupted, the purgeLock step won't be executed.
> Thus the lock won't be released.
> Meanwhile, the lock operation should also consider the interrupt cases.
