[jira] [Created] (HDFS-11639) Encode the BlockAlias in the client protocol

Ewan Higgs created HDFS-11639:
---------------------------------

             Summary: Encode the BlockAlias in the client protocol
                 Key: HDFS-11639
                 URL: https://issues.apache.org/jira/browse/HDFS-11639
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: hdfs
            Reporter: Ewan Higgs
            Assignee: Ewan Higgs


As part of the {{PROVIDED}} storage type, we have a {{BlockAlias}} type which encodes information about where the data comes from. i.e. URI, offset, length, and nonce value. This data should be encoded in the protocol ({{LocatedBlockProto}} and the {{BlockTokenIdentifier}}) when a block is available using the PROVIDED storage type.
