Zhe Zhang commented on HDFS-7907:
---------------------------------
Thanks Jing for the patch! I haven't finished but have some early comments:
# We can also have the block ID translation logic on DN. When receiving any
read or delete commands with a group ID, it should always be able to find the
individual block that it stores. I haven't read that part of DN code so am not
sure how efficient it would be. This is like a gatekeeper and might be
logically simpler than taking care of the translation in NN whenever talking to
a DN.
# Nits in {{getStorageBlock}}:
#* A minor error in comment "Identify the block stored in the given the
datanode storage"
#* How about {{getBlockOnStorage}}?
> Update DecommissionManager to support striped blocks
