> "yarn.resourcemanager.nodes.include-path" default value is "", if we need add
> one include file. and we must restart the RM.
> I suggest that adding one include or exclude file, no need restart the RM.

> NN is the same.
> Modify the HostsFileReader class:
> public HostsFileReader(String inFile,
> String exFile)
> to
> public HostsFileReader(Configuration conf,
> String NODES_INCLUDE_FILE_PATH,String
> DEFAULT_NODES_INCLUDE_FILE_PATH,
> String NODES_EXCLUDE_FILE_PATH,String
> DEFAULT_NODES_EXCLUDE_FILE_PATH)
> and thus, we can read the config file dynamic. and no need to restart the
