Bryan,
Yes, an HBase client upgrade makes sense for the Java 10 upgrade path. However,
the NoClassDefFoundError is more mysterious and does concern me.
Thanks,
Adam

Adam,
Yes for now Java 8 is what is fully supported.
Hopefully the remaining issues can be resolved in the not too distant
future to become compatible with Java 9+.
I know in the HBase case it requires changing to a newer version of
the client because the 1.1.2 client has the code that caused the issue
you ran into with "Unexpected version format: 10.0.1".
Thanks,
Bryan
