    ...Thinking about this; it might be possible to go to hive with a shaded kryo, with the invocation of those methods which exchange kryo types referring to the shaded values. That doesn't do anything for marshalling stuff between kryo versions

    Seemingly none that affect us so far. There are some binary incompatibilities in `KryoPool` (it became an interface), but that's not going to impact Spark itself.

    https://github.com/apache/spark/pull/12076#issuecomment-205690484
  
    My understanding so far:
    
    - [Marcelo showed](https://github.com/apache/spark/pull/12076#issuecomment-204129446) that we can use shaded Kryo in Hive.
    - While the Protobuf shading might have originally been introduced for Hadoop 1.x support, it's probably a good idea to keep the shading because Protobuf is a conflict-prone dependency.
    - We can't use the regular `hive-exec` artifacts because they package tons of dependencies without relocation.
    - We can't use the `core`-classified `hive-exec` 1.2.1 artifacts because they don't shade the things that we need shaded. Even if we could use this artifact, it is a pain to consume because its POM does not declare required dependencies, so we have to manually add all of Hive's transitive deps as direct deps. We've already sort of done this, but I believe that it's unnecessary and am in the process of undoing a lot of those changes as part of #1217.
    
    Therefore, I think there's no avoiding having to publish another custom Hive 1.2.1 build. I propose that we do so by editing the 1.2.1-spark POM to restore Kryo shading. I'll work on this tomorrow and loop back to this discussion once I've completed the required Hive dep. bumps.

    1. Hive uses Kryo "the guava of serialization" internally; I don't know the specifics, but its not insignificant.
    1. they moved ahead of spark's version to fix some bugs; that's the kryo which repackaged things. 
    1. Kryo types were used across methods called from Spark; the unshading was needed to get things to link, same with the switch from 2.22 to 2.21 (and a change to some files). It was less traumatic to push Hive back slightly than to try to force an update into unknown territory for chill & dependencies, even if it were possible.
    
    Upgrading to hive 2 would finally get everything in sync: ideally eliminate the need to have a custom hive JAR at all. Essentially all spark needs is a version of Hive with parameters that can be exchanged across all needed methods, with the conflict packages shaded, and the non-conflict packages generally omitted
    
    If you want to find out where things don't link, edit the spark pom to pull in org.apache.hive/hive and see what breaks.
    
    
    (of course, the other thing that would be nice would be for Hive to make it possible to subclass their thrift service cleanly; I've got a PoC of that somewhere ... it's not hard to add)

    I don't recall doing any reflection related stuff to work with kryo; problems were showing up in compilation.
    
    There's one more thing to worry about, hive minimal vs uber jars. It may still be necessary to have a custom 1.2.x JAR, just to keep all the other cruft out.

    Grepping `sql/hive` for `kryo` turns up one explicit usage in HiveShim's `HivefunctionWrapper` where it looks like we take an instance of `Kryo` provided by Hive and use that instance to deserialize things: https://github.com/apache/spark/blob/8ba2b7f28fee39c4839e5ea125bd25f5091a3a1e/sql/hive/src/main/scala/org/apache/spark/sql/hive/HiveShim.scala#L171. Assuming that we use a shaded Kryo in Hive, I think we could just import the shaded Kryo here and use that import in our `[de]serializeObjectByKryo` methods' signatures.
    
    I don't spot any other Hive-specific uses of Kryo which look problematic, so it seems plausible that we can shade without major problems. Am I overlooking other uses of Kryo to exchange data between Spark and Hive internals?

    quick glance, it looked to me like the failures were hive related. I don't know if you use any hive code, but could the fact that hive also uses kryo create a diamond that gives a runtime failure?
    
    Just a shot in the dark.

    Makes sense. Note that getting the SBT dependencies to match maven's was a complete nightmare; it'd probably have been easier to write a new version reconciler for ivy than solve it for spark alone. You shouldn't have to do much to that listing as it stands today, but updating to later hive versions will probably hurt again.
    
    FWIW, Hadoop 2.x isn't going to increment protobuf, I'm confident of that to the extent that there are enough people who would veto any attempt. Worry more about guava and jackson

    Huh, weird. It looks like this somehow _is_ a legitimate failure. I'll investigate.

    The Hive conflict should now be fixed now that #12215 has been merged, so I've updated this and am planning to merge as soon as tests pass.

    Btw, we'll have a kryo 3.1.0 release soon (depends on pending fixes regarding handling of generics). This will contain an incompatibility regarding Closure handling (https://github.com/EsotericSoftware/kryo/pull/415), not sure if that's relevant for you.
