----------------------------------

             Summary: Fail on invoking declineCheckpoint remotely
                 Key: FLINK-14519
                 URL: https://issues.apache.org/jira/browse/FLINK-14519
             Project: Flink
          Issue Type: Bug
          Components: Runtime / State Backends
    Affects Versions: 1.9.1
            Reporter: Jiayi Liao


On invoking declineCheckpoint, the reason field of DeclineCheckpoint is not serializable when
 it is a RocksDBException because org.rocksdb.Status doesn't implement serializable.

Execption:


{panel:title=My title}
Caused by: java.io.IOException: Could not serialize 0th argument of method declineCheckpoint.
This indicates that the argument type [Ljava.lang.Object; is not serializable. Arguments have
to be serializable for remote rpc calls.
