Rakesh R updated HDFS-12911:
----------------------------
Resolution: Fixed
Fix Version/s: HDFS-10285
Status: Resolved (was: Patch Available)
Thank you all for the useful discussions to define {{Context}} interface and
making a path to internal/external SPS plug-in approach. I believe {{Context}}
interface is evolving good.
It would be great if you could take the latest branch code and help in reviews.
If any comments we are happy to incorporate in the continuation jira tasks.
Thanks!
I've committed the latest patch to our branch HDFS-10285. Thanks Uma!
