-------------------------------------------------------------------

Of course!  I can provide more information tomorrow but my experience is mostly 
anecdotal.  That is, I was using the default partitioner (sort) when I 
encountered this issue and when I switched to the hash partitioner it went 
away.  Using snappy in both cases afaict.

This is what I remember off the top of my head:

Spark 1.5
Mesos 0.23.1

I don't have the stacktrace on me, but I remember it started the same as this 
above:

{code}
com.esotericsoftware.kryo.KryoException: java.io.IOException: failed to 
uncompress the chunk: PARSING_ERROR(2)
        at com.esotericsoftware.kryo.io.Input.fill(Input.java:142)
{code}

I'll set a reminder to get the rest of this to you tomorrow!
