Subject [jira] [Commented] (HDFS-2581) Implement protobuf service for JournalProtocol
Date Mon, 05 Dec 2011 03:25:43 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13162574#comment-13162574
] 

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.
