Harsh J moved HADOOP-8351 to YARN-116:
--------------------------------------

          Component/s:     (was: util)
                       nodemanager
    Affects Version/s:     (was: 0.23.1)
                       2.0.0-alpha
                  Key: YARN-116  (was: HADOOP-8351)
              Project: Hadoop YARN  (was: Hadoop Common)
    
> Add exclude/include file , need restart NN or RM.

> "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. only execute the refresh command.
> 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 NM/NN.
