Haohui Mai commented on HDFS-9525:
----------------------------------
bq. No. It's extremely useful to be able to do this from a workflow engine
e.g., Oozie.
I'm confused. Why Oozie is able to set the configuration but not the
environment variable? From the mechanism point of view they are equivalent. It
only makes a difference if Oozie can only support a single set of
configurations for every single workflow.

> When using the webhdfs:// filesystem (especially from distcp), we need the
> ability to inject a delegation token rather than webhdfs initialize its own.
> This would allow for cross-authentication-zone file system accesses.
