             Summary: Tez HashTableLoader attempts to allocate more memory than available when HIVECONVERTJOINNOCONDITIONALTASKTHRESHOLD exceeds process max mem
                 Key: HIVE-10711
                 URL: https://issues.apache.org/jira/browse/HIVE-10711
             Project: Hive
          Issue Type: Bug
            Reporter: Jason Dere
            Assignee: Jason Dere


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.
