Subject [jira] Commented: (HADOOP-6685) Change the generic serialization framework API to use serialization-specific bytes instead of Map<String,String> for configuration
Date Tue, 16 Nov 2010 09:35:18 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12932392#action_12932392
] 

Luke Lu commented on HADOOP-6685:
---------------------------------

THRIFT-363 addresses the thrift maven deploy, even though it's not completely resolved. We
should help resolving it, as they're voting for the 0.6.0 release. Checking in an external
dependency should be the last resort as any projects (hdfs, mapreduce etc. along with their
contrib srcs) that depend on hadoop-common artifacts will have to be modified manually to
include the jar in the source trees. libthrift.jar needs a version string (e.g. libthrift-0.5.0.jar)
as well, if we decide to check it in.

> Currently, the generic serialization framework uses Map<String,String> for the
serialization specific configuration. Since this data is really internal to the specific serialization,
I think we should change it to be an opaque binary blob. This will simplify the interface
for defining specific serializations for different contexts (MAPREDUCE-1462). It will also
move us toward having serialized objects for Mappers, Reducers, etc (MAPREDUCE-1183).
