@tillrohrmann can you have a look at this?
> off-heap limits set to conservatively in cluster environments
> -------------------------------------------------------------
>
> Key: FLINK-7400
> URL: https://issues.apache.org/jira/browse/FLINK-7400
> Project: Flink
> Issue Type: Bug
> Components: Cluster Management, Mesos, YARN
> Affects Versions: 1.3.0, 1.3.1, 1.3.2
> 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.
