Ming Ma created YARN-5072:
-----------------------------
Summary: Support comma separated list of includes and excludes
files
Key: YARN-5072
URL: https://issues.apache.org/jira/browse/YARN-5072
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Ming Ma
Normally a yarn cluster shares the same hosts as the underlying HDFS cluster.
To make admin easier, we have {{yarn.resourcemanager.nodes.include-path}} point
to the same file or symlink of the {{dfs.hosts}} file used by HDFS.
If we want to set up a yarn cluster to run on the same hosts of several HDFS
clusters combined, it means {{yarn.resourcemanager.nodes.include-path}} should
be able to point to a list of files each of which belongs to one HDFS cluster.
Backward compatibility, it seems ok to continue to reuse
{{yarn.resourcemanager.nodes.include-path}} as long as it can still take a
single file.
