             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.
