This turned out to be the problem for below question
Apache flink - job simple windowing problem - java.lang.RuntimeException: segment has been freed - Mini Cluster problem
So I wanted to ask by giving specific detail.
Adding a very simple windowing operator to job causes below error in MINI CLUSTER ENVIRONMENT:
Caused by: java.lang.RuntimeException: segment has been freed

When I deploy it to test cluster this problem does NOT occur?
Is there any special setting for local execution?
Please advise
