  1. Nice to see, all at one place.

    1) Looks following missed the JIRA ID, wn't be good to give JIRA IDS..?

    • API-based scheduler configuration
    • Resource profiles
    • HDFS Storage Policy Satisfier
    • HDFS tiered storage
    • ..........

    2) Duplicate entries for erasure coding.

    3) Looks some features are missed for 3.0 release.  E.G. Aliyun Object Storage,MapReduce task-level native optimization..etc

    1. Thanks, I added the missing elements from the 3.0.0-alpha4 and started to reformat the 3.0 section and adding the JIRA ids.

  2. Subramaniam Krishnan, is it better to include release date in sub title, like "Ver 2.9.0 (3rd Nov, 2017)"?

    1. I prefer to not include release dates in sub titles (yet), at least till we get more disciplined. The major.minor version is anyways is an unique identifier, thanks.

  3.  Given that dot or Minor releases shouldn't break the compatibility.,I prefer we should have compatible report before we ship 3.2 as we merging so many features..?
