Thank you Brahma for pushing this. As you mentioned, we have already taken most of the changes into production. I want to highlight that the main contribution is the addition of security. We have been able to test this at a smaller scale (~500 servers and 4 subclusters) and the performance is great with our current ZooKeeper deployment. I would also like to highlight that all the changes are constrained to hadoop-hdfs-rbf and there is no differences in commons or HDFS.
