Description

Hadoop 3.3.0 upgraded protocol buffers to 3.7.1 and RPC code have been changed. This change will cause compile failure in Ozone.

Vinayakumar is fixing this in Hadoop-side (HADOOP-17046) but it would be better for Ozone to avoid the usage of Hadoop @Private classes to make Ozone a separate project from Hadoop.
