------------------------------
Hi Josh,
I was able to reproduce this error, this error happened when the cluster is in
heavy load, in addition the task is large scale(3T input data, 1T shuffle).
Here's the stack:

uncompress the chunk: PARSING_ERROR(2)

> Identify cause of Kryo+Snappy PARSING_ERROR

> Key: SPARK-3630
> URL: https://issues.apache.org/jira/browse/SPARK-3630
> Project: Spark
> Issue Type: Task
> Components: Spark Core
> Affects Versions: 1.1.0, 1.2.0
> Reporter: Andrew Ash
> Assignee: Josh Rosen
>
> A recent GraphX commit caused non-deterministic exceptions in unit tests so
> it was reverted (see SPARK-3400).
> Separately, [~aash] observed the same exception stacktrace in an
> application-specific Kryo registrator:
> {noformat}
> com.esotericsoftware.kryo.KryoException: java.io.IOException: failed to
> uncompress the chunk: PARSING_ERROR(2)

> This ticket is to identify the cause of the exception in the GraphX commit so
> the faulty commit can be fixed and merged back into master.
