Xuan Gong commented on YARN-1759:
---------------------------------
Could you explain more on why do you think this will cause any issues. Because
I do not think there will be any.
We have two ConfigurationProvider right now.
The first one is LocalConfigurationProvider. By using this, we will load local
core-site.xml and local yarn-site.xml twice. I think this should be fine. It
will not change any property values.
The other one is FileSystemBasedConfigurationProvider. We will load local
core-site.xml and local yarn-site.xml first as the bootstrap configurations,
then we load the remote Configurations to over-write everything. And I think if
we choose to use FileSystemBasedConfigurationProvider, we should upload the
configurations that we want to use to remote FileSystems.
