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
