Shashank Agarwal commented on FLINK-7756:
-----------------------------------------
Hi [~kkl0u]
I have checked all the logs. These are the only error warn logs getting
printed. It's printing same logs for all the operators. I also thought may be
there's some other reason. But these are the only logs.
> 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.
