Subject Re: LeaseExpiredExceptions and temp side effect files
Date Fri, 21 Aug 2015 20:03:38 GMT
Hey,

Jeff graciously agreed to try it out.

I'm afraid we're still getting failures on that instance type, though with
0.11 with the patches, the cluster ended up in a state that no new
applications could be submitted afterwards.

The errors when running the pipeline seem to be similarly HDFS related.
It's quite odd.

Examples when using 0.11 + the patches:
