Subject Re: [DISCUSS] Merge HDFS-13891(RBF) to trunk
Date Mon, 03 Jun 2019 05:19:02 GMT
Thanks Brahma for starting the discussion.
I'm +1 for merging this.

FYI: In Yahoo! JAPAN, deployed all these changes in 20 nodes cluster
with 2 routers (not in production) and running several tests.

Regards,
Akira
