-------------------------------
Summary: Detailed errors from some tasks are not displayed to the
client because the tasks don't set exception when they fail
Key: HIVE-19204
URL: https://issues.apache.org/jira/browse/HIVE-19204
Project: Hive
Issue Type: Improvement
Components: Query Processor
Affects Versions: 3.0.0
Reporter: Aihua Xu
Assignee: Aihua Xu
In TaskRunner.java, if the tasks have exception set, then the task result will
have such exception set and Driver.java will get such details and display to
the client. But some tasks don't set such exceptions so the client won't see
such details unless you check the HS2 log.

exitVal = tsk.executeTask(ss == null ? null : ss.getHiveHistory());
} catch (Throwable t) {
if (tsk.getException() == null) {
tsk.setException(t);
}
LOG.error("Error in executeTask", t);
}
result.setExitVal(exitVal);
if (tsk.getException() != null) {
result.setTaskError(tsk.getException());
}
}
