Nico Kruber created FLINK-7400:

             Summary: off-heap limits set to conservatively in yarn
                 Key: FLINK-7400
             Project: Flink
          Issue Type: Bug
          Components: YARN
    Affects Versions: 1.3.2, 1.3.1, 1.3.0
            Reporter: Nico Kruber
            Assignee: Nico Kruber

Inside {{ContaineredTaskManagerParameters}}, since FLINK-6217, the 
{{offHeapSize}} is set to the amount of memory Flink will use off-heap which 
will be set as the value for {{-XX:MaxDirectMemorySize}} in various cases. This 
does not account for any off-heap use by other components than Flink, e.g. 
RocksDB, other libraries, or the JVM itself.

We should add the {{cutoff}} from the {{CONTAINERIZED_HEAP_CUTOFF_RATIO}} 
configuration parameter to {{offHeapSize}} as implied by the description on 
what this parameter is there for.
