Ming Ma updated YARN-5072:
--------------------------
Description:
When a yarn cluster shares the same hosts as the underlying HDFS cluster, we
have {{yarn.resourcemanager.nodes.include-path}} point to the same file or
symlink of the {{dfs.hosts}} file used by HDFS to make admin easier.
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.
