Sanjay Radia commented on HDFS-2581:
------------------------------------
# Rename JournalProtocolTranslatorR23 to JournalProtocolTranslatorPB (in
package hdfs.protocolProtocolBuffers)
Suggestion: change null to NULL_CONTROLLER in the rpc calls.
# JournalPBProtocolImpl - Please call it JournalProtocolServerSideTranslatorPB
to be consistent with the naming convention in writables and to reflect that
this is the SS of of JournalProtocolTranslatorPB. The real impl is inside the
NN.
Change javadoc comment to:
This is the server side translator that forwards the request to the real impl
of the protocol after translating the parameters from PB types to the native
type of the implementation.
# JournaPBProtocol - rename to JournalProtocolPB
Add the annnotation
ProtocolInfo(protocolName=org.apache.hadoop.hdfs.server.protocol.JournalProtocol
(define a constant). You can also add a version number to the annotation
instead of the static VersionID.
