[PR] HDDS-14425. Implement Ratis follower read exception handling [ozone]
ivandika3 opened a new pull request, #9811:
URL: https://github.com/apache/ozone/pull/9811
## What changes were proposed in this pull request?
It might be possible for Ratis to throw ReadIndexException if the follower is not able to get the ReadIndex one way or another (e.g. majority OMs are down). Additionally ReadException will be thrown for any pending requests. However, currently this is not handled by both the OM server and client.
OM need to throw these exceptions to prevent NPE similar to [HDDS-10918](https://issues.apache.org/jira/browse/HDDS-10918). Client can parse these exceptions and log it.
## What is the link to the Apache JIRA
https://issues.apache.org/jira/browse/HDDS-14425
## How was this patch tested?
Unit test.
