---------------------------------------
Summary: Flink 1.3 checkpointing failing with
KeyedCEPPatternOperator
Key: FLINK-6954
URL: https://issues.apache.org/jira/browse/FLINK-6954
Project: Flink
Issue Type: Bug
Components: CEP, DataStream API, State Backends, Checkpointing
Affects Versions: 1.3.0
Environment: yarn, flink 1.3, HDFS
Reporter: Shashank Agarwal
After upgrading to Flink 1.3 Checkpointing is not working, it's failing again
and again. Check operator state. I have checked with both Rocks DB state
backend and FS state backend. Check stack trace.
