> Query state is changed to QUERY_ERROR when QueryEventType.INTERNAL_ERROR
> occurs, and QueryFinishEventHandler invoked.
> However, there is no check logic for QUERY_ERROR. So stopQuery() never
> called.
> QueryMasterTask.java
> {code}
> private class QueryFinishEventHandler implements
> EventHandler<QueryMasterQueryCompletedEvent> {
> @Override
> public void handle(QueryMasterQueryCompletedEvent event) {
> QueryId queryId = event.getQueryId();
> LOG.info("Query completion notified from " + queryId);
> while (!isTerminatedState(query.getState())) {
> try {
> synchronized (this) {
> wait(10);
> }
> } catch (InterruptedException e) {
> LOG.error(e);
> }
> }
> LOG.info("Query final state: " + query.getState());
> queryMasterContext.stopQuery(queryId);
> }
> private boolean isTerminatedState(QueryState state) {
> return
> state == QueryState.QUERY_SUCCEEDED ||
> state == QueryState.QUERY_FAILED ||
> state == QueryState.QUERY_KILLED;
