Andrey Zagrebin updated FLINK-14378:
------------------------------------
Component/s: Runtime / State Backends
> Cleanup rocksDB lib folder if fail to load library
> --------------------------------------------------
>
> Key: FLINK-14378
> URL: https://issues.apache.org/jira/browse/FLINK-14378
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / State Backends
> Reporter: Yun Tang
> Priority: Major
>
> This improvement is inspired due to some of our machines need some time to
> load the rocksDB library. When some other unrecoverable exceptions continue
> to happen and the process to load library would be interrupted which cause
> the {{rocksdb-lib}} folder created but not cleaned up. As the job continues
> to failover, the {{rocksdb-lib}} folder would be created more and more. We
> even come across that machine was running out of inodes!
> Details could refer to current
> [implementation|https://github.com/apache/flink/blob/80b27a150026b7b5cb707bd9fa3e17f565bb8112/flink-state-backends/flink-statebackend-rocksdb/src/main/java/org/apache/flink/contrib/streaming/state/RocksDBStateBackend.java#L860]
