Aaron T. Myers commented on HDFS-2843:
--------------------------------------
Hey Suresh, I'm not convinced that this name change is appropriate. I agree
that most of this information should not differ between storage directories on
a single node, but some of the information is still storage-specific (e.g.
layoutVersion), and the information is mostly used to compare storage versions
between nodes. Given this, the current name seems appropriate to me. I could
probably be convinced otherwise, though.
Regardless, if we do go ahead with a name change, it doesn't make sense to me
that we would change StorageInfoProto but not StorageInfo itself, given that
StorageInfoProto is really just a serialization class of StorageInfo. If the
semantic of the name StorageInfoProto is wrong, then surely StorageInfo is as
well, right?

> StorageInfoProto has cTime, layoutVersion, namespaceID and clusterID. This is
