Subject RocksDBStatebackend does not write checkpoints to backup path
Date Tue, 26 Mar 2019 09:46:01 GMT

I have a job (with Flink 1.6.4) which uses rocksdb incremental checkpointing, but the checkpointing
always fails with `IllegalStateException`, 
because hen performing `RocksDBIncrementalSnapshotOperation`, rocksdb finds that `localBackupDirectory`,
which should be created earlier
by rocksdb checkpoint, doesn’t exist. But there is no error message about failures of rocksdb

What could possibly be the cause? Thanks a lot!
