[jira] [Created] (FLINK-7756) RocksDB state backend Checkpointing
(Async and Incremental) is not working with CEP.
Shashank Agarwal created FLINK-7756:
---------------------------------------
Summary: RocksDB state backend Checkpointing (Async and Incremental) is not working with CEP.
Key: FLINK-7756
URL: https://issues.apache.org/jira/browse/FLINK-7756
Project: Flink
Issue Type: Bug
Components: CEP, State Backends, Checkpointing, Streaming
Affects Versions: 1.3.2
Environment: Flink 1.3.2, Yarn, HDFS, RocksDB backend
Reporter: Shashank Agarwal
When i try to use RocksDBStateBackend on my staging cluster (which is using HDFS as file system) it crashes. But When i use FsStateBackend on staging (which is using HDFS as file system) it is working fine.
On local with local file system it's working fine in both cases.
Please check attached logs. I have around 20-25 tasks in my app.
