Looks like this exception is after many more failures have occurred. It is
already on attempt 6 for stage 7 -- I'd try to find out why attempt 0
failed.
This particular exception is probably a result of corruption that can
happen when stages are retried, that I'm working on addressing in
https://issues.apache.org/jira/browse/SPARK-7308. But your real problem is
figuring out why the stage failed in the first place.

Hi,
I was running our graphx application(worked finely on Spark 1.2.0) but
failed on Spark 1.3.1 with below exception.
Anyone has idea on this issue? I guess it was caused by using LZ4 codec?
