Passcode: a%hES+0R



1. Status of release 1.1:

  * Waiting for decom branch merge
  * We need a release manager (!)
  * We should start with ratis-thirdparty and ratis releases


2. environment variable migration: HADOOP_* -> OZONE_*

How to avoid usage of HADOOP_CLASSPATH if it's set in the environment 
(but it's not required for Ozone).


Follow HDDS-4525


3. (from ~0:15) Streaming data for write-path

Shashi gave a good presentation Ratis streaming and Ozone

  TLDR; manage data operations (like writeChunk) and metadata operations 
(like putBlock) in different way would provide significant performance gain.

(The real problem is more complex than this TLDR;, and there are 
multiple ways to do it, I recommend to check the recording).

Thanks,
Marton
