Subject Lost executors
Date Wed, 23 Jul 2014 15:27:54 GMT
I'm using spark 1.0.1 on a quite large cluster, with gobs of memory, etc.
 Cluster resources are available to me via Yarn and I am seeing these
errors quite often.

ERROR YarnClientClusterScheduler: Lost executor 63 on <host>: remote Akka
client disassociated

This is in an interactive shell session.  I don't know a lot about Yarn
plumbing and am wondering if there's some constraint in play -- executors
can't be idle for too long or they get cleared out.

Any insights here?
