[jira] [Updated] (YARN-5072) Support comma separated list of
includes and excludes files
[ https://issues.apache.org/jira/browse/YARN-5072?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.
