Rob Leidle created TEZ-3238:
-------------------------------
Summary: Shuffle service name should be configureable and should
not be hardcoded to ‘mapreduce_shuffle’
Key: TEZ-3238
URL: https://issues.apache.org/jira/browse/TEZ-3238
Project: Apache Tez
Issue Type: Improvement
Affects Versions: 0.8.2
Reporter: Rob Leidle
In YARN there are no guarantees that a shuffle service with a specific name
exists. The setting '
yarn.nodemanager.aux-services’ can be filled with a list of names that can be
defined by the Hadoop cluster administrator. It is merely by convention that
many clusters have their MapReduce shuffle service named ‘mapreduce_shuffle’.
Tez is hard-coded to use a shuffle service named ‘mapreduce_shuffle’:
https://github.com/apache/tez/blob/TEZ-8/tez-api/src/main/java/org/apache/tez/dag/api/TezConstants.java#L75.
This name should be configureable. Also, this is a hidden dependency of Tez,
we should add that the shuffle service is a dependency to the Tez
documentation.
