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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
