Alexander Pivovarov commented on HIVE-10711:
--------------------------------------------

Jason, do you think it's better to add new tez configuration parameter for 0.5?
{code}
noConditionalTaskThreshold = (long) (processMaxMemory * 0.5);
{code}

> Tez HashTableLoader attempts to allocate more memory than available when 
> HIVECONVERTJOINNOCONDITIONALTASKTHRESHOLD exceeds process max mem

> Tez HashTableLoader bases its memory allocation on 
> HIVECONVERTJOINNOCONDITIONALTASKTHRESHOLD. If this value is largeer than the 
> process max memory then this can result in the HashTableLoader trying to use 
> more memory than available to the process.
