Zhe Zhang commented on HDFS-9312:
---------------------------------

Thanks for the work Eddy. The patch LGTM overall.

The only issue I see is that we should have a better name for 
{{injectReplicas}}: 1) it only injects 1 replica; 2) it took me a while to 
realize it injects a _corrupt_ replica. Maybe something like 
{{injectCorruptReplica}}?

+1 pending Jenkins and after addressing the above.

> Fix TestReplication to be FsDataset-agnostic.

> {{TestReplication}} uses raw file system access to inject dummy replica 
> files. It makes {{TestReplication}} not compatible to non-fs dataset 
> implementation.
> We can fix it by using existing {{FsDatasetTestUtils}}.
