Arun, I propose the following changes for 2.3: - There have been a lot of improvements related to supporting http policy. - There is a still discussion going on, but I would like to deprecate BackupNode in 2.3 as well. - We are currently working on rolling upgrades related change in HDFS. We might add a couple of changes that enables rolling upgrades from 2.3 onwards (hopefully we can this done by December)
I propose the following for 2.4 release, if they are tested and stable: - Heterogeneous storage support - HDFS-2832 - Datanode cache related change - HDFS-4949 - HDFS ACLs - HDFS-4685 - Rolling upgrade changes Let me know if you want me to update the wiki.
