      I'm getting intermittent but repeatable 500s when trying to view the status of some Oozie workflows in Hue – /oozie/list_oozie_workflow endpoint. I turned on debug and have attached the 500 html.

      This started happening after we upgraded to CDH 5.4.0 but it doesn't happen on all jobs. I cannot seem to figure out a pattern for what jobs it fails on what jobs it doesn't. At first I thought it had something to do with the problems we had with the V2 editor (since disabled) – there appeared to be multiple workflows for the same user with the same name. However, I'm still getting the errors even after freshly creating a new workflow (xml is attached). I'm also getting this error when browsing status of workflow jobs from a few long running coordinators (but not all such long running jobs for this user).

      I have tried resynchronizing the DB, but that had no effect.

      Status in the Oozie console looks normal (attached), as it does in the Yarn RM, so I think it's just a Hue problem.

      Sorry for dropping so many bugs on you guys today, but CDH 5.4.0 has been a bit of minefield for us.
