Kirill A. Korinskiy created FLINK-8809:
------------------------------------------

             Summary: Decrease maximum value of DirectMemory
                 Key: FLINK-8809
                 URL: https://issues.apache.org/jira/browse/FLINK-8809
             Project: Flink
          Issue Type: Bug
          Components: TaskManager
            Reporter: Kirill A. Korinskiy


Good day!

 

Have I can see since this [commit|https://github.com/apache/flink/commit/6c44d93d0a9da725ef8b1ad2a94889f79321db73] TaskManager uses 8,388,607 terabyte as maximum out of heap memory. I guess that not any system has so much memory and it may be a reason to kill java process by OOM Killer.

 

I suggest to decrease this value to reasonable value by default.

 

Thanks
