> {{ContainerMerkleTreeTestUtils}} currently uses random placement for block and chunk errors in methods like [this|https://github.com/apache/ozone/blob/f1679cee6668550eef76ffb870be11db4d8c28df/hadoop-hdds/container-service/src/test/java/org/apache/hadoop/ozone/container/checksum/ContainerMerkleTreeTestUtils.java#L181]. This will be difficult to diagnose with our current testing setup since it may fail intermittently and we will not know what configuration was used. We would then have to use a set configuration to test the fix.
> Our current test infra is not well set up for fuzz testing and the current test suites are expected to have more deterministic behavior, so we should instead handle specifying the placement of the failures instead of just the number of failures and placing them randomly.
