Re: HDFS Protocol Documentation
Please see the .proto files:

RPC implementation:
./hadoop-common-project/hadoop-common/src/main/proto/hadoop_rpc.proto

Protocols used in HDFS. See the corresponding java classes and javadoc for
additional information.
./hadoop-hdfs-project/hadoop-hdfs/src/main/proto/ClientDatanodeProtocol.proto
./hadoop-hdfs-project/hadoop-hdfs/src/main/proto/ClientNamenodeProtocol.proto
./hadoop-hdfs-project/hadoop-hdfs/src/main/proto/DatanodeProtocol.proto
./hadoop-hdfs-project/hadoop-hdfs/src/main/proto/datatransfer.proto
./hadoop-hdfs-project/hadoop-hdfs/src/main/proto/GetUserMappingsProtocol.proto
./hadoop-hdfs-project/hadoop-hdfs/src/main/proto/HAZKInfo.proto
./hadoop-hdfs-project/hadoop-hdfs/src/main/proto/hdfs.proto
./hadoop-hdfs-project/hadoop-hdfs/src/main/proto/InterDatanodeProtocol.proto
./hadoop-hdfs-project/hadoop-hdfs/src/main/proto/JournalProtocol.proto
./hadoop-hdfs-project/hadoop-hdfs/src/main/proto/NamenodeProtocol.proto
./hadoop-hdfs-project/hadoop-hdfs/src/main/proto/RefreshAuthorizationPolicyProtocol.proto
./hadoop-hdfs-project/hadoop-hdfs/src/main/proto/RefreshUserMappingsProtocol.proto

There are similar files for YARN as well.
