Gabor Feher commented on SPARK-3630:
------------------------------------
Notes:
- I was able to repeat this error.
- The cluster was under heavy load: there was 10*19GB executor memory
available, while an RDD of size 380GB was being processed.
- As it turns out, I was using snappy version 1.0.4 along with Spark 1.6.0,
which is older than the one bundled in spark1.6+hadoop builds.
- I have switched "spark.io.compression.codec" to "lz4" and now the problem
seems to be gone.

> 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)
