---------------------------------

             Summary: ContaineredTaskManagerParameters sets off heap memory size incorrectly
                 Key: FLINK-6217
                 URL: https://issues.apache.org/jira/browse/FLINK-6217
             Project: Flink
          Issue Type: Bug
            Reporter: Haohui Mai
            Assignee: Haohui Mai


Thanks [~bill.liu8904] for triaging the issue.

When {{taskmanager.memory.off-heap}} is disabled, we observed that the total memory that Flink allocates exceed the total memory of the container:

For a 8G container the JobManager starts the container with the following parameter:

{noformat}
$JAVA_HOME/bin/java -Xms6072m -Xmx6072m -XX:MaxDirectMemorySize=6072m ...
{noformat}

The total amount of heap memory plus the off-heap memory exceeds the total amount of memory of the container. As a result YARN occasionally kills the container.
