Sanjay Radia commented on HADOOP-6685: -------------------------------------- @Doug> Progress stopped on HADOOP-6659 when Eric vetoed my incremental approach Doug, at least a couple of folks asked for a design doc and fuller plan; you did not provide it. Doug you added a dependency on Avro in RPC without providing a plan on how all the pieces are put together. Indeed it is more than just a library dependency - there are avro related annotations. While I am a fan of Avro (being part of the team that created it at Yahoo), I see no problems in adding first class support for PB since it is a robust serialization framework. When I let the Avro dependency creep into Hadoop I did not think that Doug would be opposed to adding support for PB in the future. Both need to be supported in a first class way. My feeling is that Avro will prevail in the long term but right now PB addresses the needs of many users. > Change the generic serialization framework API to use serialization-specific > bytes instead of Map<String,String> for configuration > ---------------------------------------------------------------------------------------------------------------------------------- > > Key: HADOOP-6685 > URL: https://issues.apache.org/jira/browse/HADOOP-6685 > Project: Hadoop Common > Issue Type: Improvement > Reporter: Owen O'Malley > Assignee: Owen O'Malley > Fix For: 0.22.0 > > Attachments: libthrift.jar, serial.patch, serial4.patch, > serial6.patch, serial7.patch, SerializationAtSummit.pdf > > > Currently, the generic serialization framework uses Map<String,String> for > the serialization specific configuration.
