Subject [jira] Commented: (AVRO-593) Avro mapreduce apis incompatible with hadoop 0.20.2
Date Fri, 29 Oct 2010 20:46:20 GMT

    [ https://issues.apache.org/jira/browse/AVRO-593?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12926450#action_12926450

Scott Carey commented on AVRO-593:
----------------------------------

FYI: Wrapping Avro serialization 'inside' of Writable will work, but there will be some non-trivial
performance cost to that.  Writable requires more fine-grained reads and writes from the underlying
stream preventing optimal buffering for Avro.

> The avro api's for hadoop use the hadoop mapreduce api that has been deprecated. A new
avro mapreduce api should be implemented for hadoop 0.20 and higher.
