Unable to Reduce with Tez on Teradata Appliance Bundle HDP 2.1.7

Problem

When executing Datameer jobs on a Teradata Appliance Bundle in HDP 2.1.7, reduce jobs fail with the Tez framework.

 

Cause

This is a known configuration issue.

The following Java flag is included by Datameer by default, but does not function properly on Teradata Appliances: 

-XX:+UseNUMA

 

Solution

To resolve this issue, the Java command options need to be overridden in Datameer. Please add the following Custom Hadoop Property to the Datameer installation:

tez.am.launch.cmd-opts=-XX:+UseParallelGC
