[CONTROLLER-1287] Clustering: Merge stopped working

Thu, 19 Oct 2017 21:26:56 +0000

We've used merge since Helium.

Magically in the last day or so, merge is completely borked:

{message=canCommit encountered an unexpected failure, errorList=[RpcError [message=canCommit encountered an unexpected failure, severity=ERROR, errorType=APPLICATION, tag=operation-failed, applicationTag=null, info=null, cause=java.lang.IllegalStateException: Optional.get() cannot be called on an absent value]]}

The Group exists, I write it earlier.

I've been banging on this all day. How else is merge supposed to work if the get "behind the curtains" is going to bork on Absent?
