Zhe Zhang commented on HDFS-8619:
---------------------------------
Thanks Jing for splitting the patch for HDFS-8652!
bq. Please let me know if you need any help on either development or code
review.
Thanks for offering the help! It would be great if you can help review
HDFDS-8623 and HDFS-8653. HDFS-8623 might have some overlap with HDFS-8652
patch. Depending on how they go, I'm happy to rebase either patch.

> 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.
