[jira] [Commented] (HIVE-14669) Have the actual error reported when a q test fails instead of having to go through the logs

Laszlo Bodor commented on HIVE-14669:
-------------------------------------

[~sseth]: I think it's still an issue, a proper solution would help a lot all the developers
currently what I'm seeing is: only an error code and the source query is dropped to the console ( !01_mvn_out.png! ), but hive.log contains the full trace ( !02_hive_log.png! ), I think, displaying the latter on the console output would be great, what's your opinion?

> QTest runs end up invoking CliDriver.processLine. This, in most cases, reports a numeric exit code - 0 for success. Non-zero for various different error types (which are defined everywhere in the code).
> Internally CliDriver does have more information via CommandResult. A lot of this is not exposed though. That's alright for the end user cli - (Command line tool translating the error to a code and message). However, it makes debugging very difficult for QTests - since the log needs to be looked at each time.
> Errors generated by the actual backend execution are mostly available to the client, and information about these should show up as well. (If it doesn't - we have a usability issues to fix).
