-------------------------------------------
Ping.
It would be good to get this into 3.x.
> Improve versioning and compatibility support in native library for downstream
> hadoop-common users.

> There is no compatibility policy enforced on the JNI function signatures
> implemented in the native library. This library typically is deployed to all
> nodes in a cluster, built from a specific source code version. However,
> downstream applications that want to run in that cluster might choose to
> bundle a hadoop-common jar at a different version. Since there is no
> compatibility policy, this can cause link errors at runtime when the native
> function signatures expected by hadoop-common.jar do not exist in
> libhadoop.so/hadoop.dll.
