empty response

    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 Mattieu,

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

    Hi Dave,

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



    Hi Mathieu,

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

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

    Let me know what you find there.
