                 URL: https://issues.apache.org/jira/browse/HUDI-2099

          Issue Type: Bug

    Affects Versions: 0.8.0
         Environment: spark3.1.1

hadoop3.1.1
            Reporter: tao meng
            Assignee: tao meng
             Fix For: 0.8.0


when we acquire hive lock failed and the lock state is WATING, we should 
release this WATING lock; otherwise this hive lock will be locked forever。

test step:

use hive lock to control concurrent write for hudi, let‘s call this lock 
hive_lock

start three writers to write hudi table by using hive_lock concurrently, one of 
the writer will failed to acquire hive lock due to competition issues。

*Exception in thread "main" org.apache.hudi.exception.HoodieLockException: 
Unable to acquire lock, lock object LockResponse(lockid:76, state:WAITING)*

 

start another writer to write hudi table by using same hive_lock, then we find 
hive_lock is locked forever, we have no way to acquire it

*Exception in thread "main" org.apache.hudi.exception.HoodieLockException: 
Unable to acquire lock, lock object LockResponse(lockid:87, state:WAITING)*
