Arpit Agarwal commented on HDFS-4987:

Hi Nicholas,

Couple of comment related nitpicks we can fix later.

# BlockInfo.java:44 - Comment should be updated to say {{"block belongs to triplets[3*i] is
the reference to the StorageInfo"}}
# BlockInfo#findStorageInfo - Javadoc needs to be updated to {{"   * @param dn"}}

> Currently namenode track in BlockInfo, the corresponding DataNodeDescriptor. I propose
changing this with new abstraction StorageDescriptor. This change will also make DatanodeDescriptor
a collection of StroageDescriptors. This will allow given a block, identify its storage and
also Datanode.
