checkpointing due to multiple mappers tries to access the same file.
Key: FLINK-8098
URL: https://issues.apache.org/jira/browse/FLINK-8098
Project: Flink
Issue Type: Bug
Components: State Backends, Checkpointing
Affects Versions: 1.3.2
Environment: Yarn, HDFS 2.7.3, Kafka, scala streaming API, CEP

I am running streaming application with parallelism 6. I have enabled
checkpointing(1000). But application gets the crash after 1-2 days. After
analysing logs i found following trace.
