Subject Re: [VOTE] Merge HDFS-13891(RBF) to trunk
Date Sun, 09 Jun 2019 13:56:28 GMT
Hi All,

    Given the positive response to the discussion thread [1], here is the
formal vote thread to merge HDFS-13891 in to trunk.

    Summary of code changes:
    1. Code changes for this branch are done in the hadoop-hdfs-rbf
subproject, there is no impact to hadoop-hdfs and hadoop-common.
    2. Added Security support for RBF
    3. Added Missing Client Protocol API's
    4. Bug Fixes/ Improvments


     The vote will run for 7 days, ending Sat June 15th. I will start this
vote with my +1.

Regards,
Brahma Reddy Battula
