Subject Re: [VOTE] Release Apache Spark 1.0.1 (RC2)
Date Fri, 11 Jul 2014 16:31:24 GMT
Hi Matei,

We have not had time to re-deploy the rc today, but one thing that jumps
out is the shrinking of the default akka frame size from 10MB to around
128KB by default.  That is my first suspicion for our issue - could imagine
that biting others as well.

I'll try to re-test that today - either way, understand moving forward at
this point.

Gary
