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

             Summary: HiveDriverRunHookContext's command is null in HS2 mode
                 Key: HIVE-14343
                 URL: https://issues.apache.org/jira/browse/HIVE-14343
             Project: Hive
          Issue Type: Bug
    Affects Versions: 2.2.0
            Reporter: Chao Sun


Looking at the {{Driver#runInternal(String command, boolean alreadyCompiled)}}:
{code}
    HiveDriverRunHookContext hookContext = new 
HiveDriverRunHookContextImpl(conf, command);
    // Get all the driver run hooks and pre-execute them.
    List<HiveDriverRunHook> driverRunHooks;
{code}

The context is initialized with the {{command}} passed in to the method. 
However, this command is always null if {{alreadyCompiled}} is true, which is 
the case for HS2 mode.
