Hi Russell,
I don't think `BackendBuildingException` is root cause. In your case, this
exception appears when task is under cancelling.
Have you ever checked the log of yarn node manager? There should be an exit
code of container. Even more the container is probably killed by yarn node
manager.
Hi Flink team,
I am trying to submit flink job (version 1.8.2) with RocksDB backend to my own
yarn cluster (hadoop version 2.6.0-cdh5.7.3), the job always failed after
running for a few hours with the connection loss of some taskmanagers.
