Description

Here's a snippet from Driver.execute():

            // TODO: This error messaging is not very informative. Fix that.
            errorMessage = "FAILED: Execution Error, return code " + exitVal + " from "
                + tsk.getClass().getName();
            SQLState = "08S01";
            console.printError(errorMessage);
            if (running.size() != 0) {
              taskCleanup();
            }
            return 9;

I simply returned in case of runtime errors without maintaining SessionState. It could cause resource leak mentioned in HIVE-1959.
