[jira] [Commented] (AVRO-1439) MultipleInputs equivalent for Avro MR

["Doug Cutting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-1439?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13872353#comment-13872353 ] 

Doug Cutting commented on AVRO-1439:
------------------------------------

Harsh, this looks great and is a wonderful addition.  Some quick comments:
 - 'schemata' is a more commmon plural than 'schemae', but we've generally stuck to simply 'schemas' in Avro
 - some public stuff is missing javadoc.  we should probably also expand the AvroMultipleInputs javadoc to include a pseudo-code example, like AvroMultipleOutputs does.
 - i'm okay with the limitations (specific/reflect, no inputformats, etc) as long as we are convinced that we can compatibly remove them later.
 - we might commit the mapred version first and add the mapreduce in a subsequent issue.

> We have MultipleOutputs-like functionality for Avro today, but lack a MultipleInputs which would make pure-MR joins possible to do with Specific/Reflect Avro MR.
