>
> ORC writer has its own memory manager that assumes memory usage or memory
> available based on JVM heap (MemoryMX bean). This works on tez container mode
> execution model but not in LLAP where container sizes (and Xmx) are typically
> high and there are multiple executors per LLAP daemon. This custom memory
> manager should be aware of memory bounds per executor.
