consistency of yarn exclude file

[Dong Ye]

Hi, All:

        For resource manager, can we set
yarn.resourcemanager.nodes.exclude-path to a s3 file, so all 3 resource
managers can access it. The benefit is that there is no need to sync the
exclude.xml file. If not, how to sync the file on different HA resource
managers?

Thanks.
