If a plugin packages a conflicting dependency (say a different version of hadoop):
- the pipeline starts, and remains in initializing phase forever
- the UI shows status as RUNNING, but there's no start time
- I saw it stay in this state for over 15 mins
- there is no indication in the logs on the UI or the log file. No Mapreduce related logs appear
It would be nice if whatever the problem is, is reported to the user faster and the pipeline is marked failed.
