Re: RocksDBStatebackend does not write checkpoints to backup path

Hi Gordon,

Thanks for your reply. I’ve found out that it should be a bug of 
RocksDBStateBackend [1].

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?

Gordon

RocksDBStatebackend does not write checkpoints to backup path

[Paul Lam]

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,
Paul Lam
