Xuan Gong commented on YARN-1611:
---------------------------------
Thanks for comments, [~sandyr]
bq. Just took a quick look at the patch. Right now we have a nice one way
relationship where configs affect the services, but the services do not affect
configs. The patch appears to have the RM deleting and uploading files to the
remote config directory, which makes me nervous. Would it make sense for the
admin to be responsible for placing configs in the remote dir, and the RMs just
be responsible for pulling them down?
Yes, you are right. Will remove upload and deleting file from
RemoteConfiguration functionality.
bq. Will the existing way of doing things (writing files to disk for RMs and
calling refresh on both) still be supported?
Yes, it is still supported. In HA case, if there is no remote configuration, it
will give the warning message.
bq. Will the remote configuration be supported for the non-HA case?
Currently, no. This is for HA case.
