Hi,

Do you have the full error message of the failure?
A wild guess to begin with: have you made sure that there are sufficient permissions to create the directory?

Hi,

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 checkpoint. 

What could possibly be the cause? Thanks a lot!

Best,
