> Project: Hadoop YARN
> Issue Type: Bug

> Affects Versions: 2.0.0-alpha
> Reporter: xieguiming
> Assignee: xieguiming
> Fix For: 2.0.3-alpha, 0.23.5

> The "yarn.resourcemanager.nodes.include-path" default value is "", if we need
> to add an include file, we must currently restart the RM.
> I suggest that for adding an include or exclude file, there should be no need
> to restart the RM. We may only execute the refresh command. The HDFS NameNode
> already has this ability.
> Fix is to the modify HostsFileReader class instances:
> From:
> {code}
> public HostsFileReader(String inFile,
> String exFile)
> {code}
> To:
> {code}
> 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)
> {code}
> And thus, we can read the config file dynamically when a {{refreshNodes}} is
> invoked and therefore have no need to restart the ResourceManager.
