Swaminathan Balachandran updated HDDS-11690:
--------------------------------------------
Description:
Write a test case to verify if ALL_COMMITED replication in ratis is respected
on Datanode pipeline writes or if we fallback to MAJORITY_COMMIT. We need to
test this out by fault injecting some code on one of the datanodes on pipeline
writes. This can be achieved by mocking one of the datanode in a
MiniOzoneCluster write code by adding a sleep to make it lagging follower in a
pipeline.
We should validate of watch for commit waits for all commit when
[https://github.com/apache/ozone/blob/a33af1dbce25ca3c1f71d833f506d8d8290a4213/hadoop-hdds/common/src/main/java/org/apache/hadoop/hdds/ratis/conf/RatisClientConfig.java#L103]
is set to ALL_COMMITED and see if the watch for commit fails when a lagging
follower fails to apply some transaction and see if the commit still happens.
