Oozie Switch Node not responding to std-out

  • #52812
    Mattie Whitmore


    I am working through the Cloudera Earthquake example ( I changed the earthquakeMinThreshold=1, so that isLarger=true and the Decide node will go to the get-data node. I checked the output of the shell script locally. It returns: largest=1.9 isLarger=true, as it should.

    The problem: when I run the workflow the decide node goes to end, as if isLarger=False. Is there something I am missing? Does this workflow need to be updated?

    I am having the same issue with my own workflow that is similar, it ONLY defaults as if std-out isn’t being captured. Does anyone know how I can debug this, how I can see what is being send between nodes in the workflow?

    The only special thing I’m doing, besides using a cloudera example on a hortonworks sandbox, is running on a pseudo distributed VM (with 4GBS) on my laptop which has Mavericks installed so it is harder to understand how memory is being allocated. Would this cause any issue?

    Thank you!
