[jira] [Created] (SPARK-21188) releaseAllLocksForTask should synchronize the whole method

Feng Liu created SPARK-21188:
--------------------------------

             Summary: releaseAllLocksForTask should synchronize the whole method
                 Key: SPARK-21188
                 URL: https://issues.apache.org/jira/browse/SPARK-21188
             Project: Spark
          Issue Type: Bug
          Components: Block Manager, Spark Core
    Affects Versions: 2.1.0, 2.2.0
            Reporter: Feng Liu


Since the objects readLocksByTask, writeLocksByTask and infos are coupled and supposed to be modified by other threads concurrently, all the read and writes of them in the releaseAllLocksForTask method should be protected by a single synchronized block. The fine-grained synchronization in the current code can cause some test flakiness.
