Louis Bergelson commented on SPARK-20389:
-----------------------------------------
What's the process for evaluating the effect on spark apps? As far as I can
tell the changes from 3->4 will mean that data serialized with an older version
of kryo will not be loadable by a new version of kryo unless you run with a
compatibility option configured. Hopefully most apps aren't storing data
that's been serialized by kryo and only using it for serialization between
processes. I don't know if this has knock on effects for things like parquet
though, does it use kryo?
We have a recurrent issue when serializing large objects that is fixed in kryo
4 and would really like to see spark updated.

> I am experiencing an issue with Kryo when writing parquet files. Similar to
> https://github.com/broadinstitute/gatk/issues/1524 a
> NegativeArraySizeException occurs. Apparently this is fixed in a current Kryo
> version. Spark is still using the very old 3.3 Kryo.
> Can you please upgrade to a fixed Kryo version.
