             Summary: ZooKeeperHiveLockManager should close after lock release in releaseLocksAndCommitOrRollback
                 Key: HIVE-18303
                 URL: https://issues.apache.org/jira/browse/HIVE-18303
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 2.2.0, 2.1.1
         Environment: hive2.1.1, jdk 1.7, centos
            Reporter: J.P Feng


i found exception :

ZooKeeperHiveLockManager: Failed to release ZooKeeper lock: 
java.lang.IllegalStateException: instance must be started before calling this method

because in ShutdownHookManager, priority of CuratorFrameworkSingleton.closeAndReleaseInstance is 10, but in Driver.releaseLocksAndCommitOrRollback, it's 0. So locks are released after CuratorFramework is closed, which may case such exception.

This is my operation:

I add hook of ExecuteWithHookContext or PreExecute, which simply sleep like:
    @Override
    public void run(HookContext hookContext) throws Exception {

        int max_i = 6;

        try {
            for ( int i = 0; i < max_i ; i ++) {
                LOG.info("try to sleep, for i is => " + i);
                Thread.sleep(5000);
            }

        } catch (Exception e) {
            LOG.error(e.getMessage(), e);
        }

    }

and run sql for example, 
select count(1) from hive_test.time_test;

Then enter ctrl+c twice to kill hive client. Hive client will not exit, and the above error is thrown.
