>
> The defaults in Ambari assume 80% of the YARN container size is allocate to
> the user heap (Xmx).
> On top of this particular restriction, the allocation blocks are divided into
> Eden/Survivor/Tenured - a single allocation spanning 40% of the heap might
> fail for tez runtime.io.sort.mb.
> Scale down the Tez sort size and map join by 0.8x to match Xmx.
