Zhe Zhang commented on HDFS-8619:
---------------------------------

Thanks Jing! I meant to say all changes, including the main 
{{CorruptReplicasMap}} change LGTM overall and look applicable for trunk. 
Should we just retarget the JIRA to trunk?

> Currently we use the same {{BlockManager#countNodes}} method for striped 
> blocks, which simply treat each internal block as a replica. However, for a 
> striped block, we may have more complicated scenario, e.g., we have multiple 
> replicas of the first internal block while we miss some other internal 
> blocks. Using the current {{countNodes}} methods can lead to wrong decision 
> in these scenarios.
