Re: Unable to run TestHiveDriver tests on latest code

Hi Yash,

Thanks for your prompt response.
I was able to see that 404 is coming from QueryExecutionServiceImpl.getResultSet method. In that method ctx is null and the query handle isn't yet stored in finished_queries table hence the NotFoundException is raised. I can run other commands like show cubes etc. I don't think its a connection issue. 

All the queries are running well from inmobi's hive cli.
I'm using Java 1.7 and maven 3.21. I was able to run Lens with the same tools earlier. 

Regards,
-Pranav.

    Hi Pranav,
    The error does not highlight a lot of info about your error but i
    believe that a 404 might be a connection issue.

    Can u check if u can access hive directly (inmobi's version of
    hive). The root cause can be identified by the testcase u
    mentioned. I feel it might be related.

    Could you share more info or error logs. Lets figure out the root
    cause if it helps.

        Hi Lens Gurus,

        I installed lens from latest and found that tests are failing:
        Running TestSuite
        Tests run: 31, *Failures: 21*, Errors: 0, Skipped: 0, Time

        I'm getting following error from CLI

        *0 rows process in (0) seconds.*

        There are 2 issues
        a) I intermittently get the result metadata failed with HTTP 404
        b) 0 rows returned.

        For each query fired via Lens I can see map reduce job getting
        initiated but the results for *all* queries is always 0 rows
        processed.

        Is this a known issue?

        Regards,
