[jira] [Commented] (FLINK-7756) RocksDB state backend Checkpointing
(Async and Incremental) is not working with CEP.
[ https://issues.apache.org/jira/browse/FLINK-7756?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16352310#comment-16352310 ]
Kostas Kloudas commented on FLINK-7756:
---------------------------------------
Hi [~shashank734],
Is there any possibility to provide us your pattern and function (or a similar one with the same characteristics) and a sample input to reproduce the problem? The reason is that so far we are not able to reproduce the problem, therefore we cannot solve it with certainty.
If you could, that would be really helpful.

> Key: FLINK-7756
> URL: https://issues.apache.org/jira/browse/FLINK-7756
> Project: Flink
> Issue Type: Sub-task
> Components: CEP, State Backends, Checkpointing, Streaming
> Affects Versions: 1.4.0, 1.3.2
> Environment: Flink 1.3.2, Yarn, HDFS, RocksDB backend
> Reporter: Shashank Agarwal
> Priority: Blocker
> Fix For: 1.5.0, 1.4.1
>
>
> 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.
