Subject [jira] [Commented] (AVRO-1170) Avro's new mapreduce APIs don't work with Hadoop 2
Date Wed, 19 Sep 2012 16:11:08 GMT

    [ https://issues.apache.org/jira/browse/AVRO-1170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13458787#comment-13458787
] 

Doug Cutting commented on AVRO-1170:
------------------------------------

For the createTaskAttemptContext stuff we should add a comment explaining the purpose of this,
to work around incompatible API changes.

For the pom.xml changes, note that the parent pom.xml sets the default version for Hadoop
in Avro to 0.20.205.0, so the change here is only for the mapred module, not for the other
modules that depend on hadoop (tools and trevni).  Perhaps that's intended, so that we end
up testing against both versions of Hadoop.  If so, we should add a comment to that effect.
 If its not intended then the version should probably be set in the parent pom.xml.  That
said, we should not add a dependency on a SNAPSHOT pom, so we'll probably not commit this
until there's a Hadoop release that contains the required changes or we figure out another
way to fix this.

> Avro does not compile against Hadoop since some interfaces were changed to classes between
Hadoop 1 and 2 (e.g. TaskAttemptContext).
