    Not sure how to reproduce, but I had a couple of times an empty response error in my browser after running a simple DDL query .
    In server logs, I see :

    [17/Jan/2014 15:46:33 +0000] resource DEBUG GET Got response: {“apps”:null}
    [17/Jan/2014 15:46:33 +0000] http_client DEBUG GET http://namenode2.poc-hadoop.XXXXXXX:8088/ws/v1/cluster/apps?user=admin&finalStatus=UNDEFINED

    (the node in the URL is the ResourceManager)

    what is the ‘UNDEFINED’ in the URL in the call to ResourceManager ?
    Is this bug described somewhere ?

    Hue version 2.3.0-76, in a fresh install of HDP2

    Hi Mathieu,

    It looks like it is the underlying infrastructure which is YARN.

    http://stackoverflow.com/questions/20506992/cant-run-a-mapreduce-job-with-yarn

    I would check the resource manager and YARN logs in /var/log/hadoop-yarn/yarn

    Let me know what you find there.

    Thanks

    Dave

    Hi Dave,

    Hue is giving this empty response. The logs are the logs collected on Hue.

    Hi Mattieu,

    Is this an issue with Hue or with YARN when you’re running a query?

    Thanks

    Dave
