Tom White updated AVRO-1170:
----------------------------
Attachment: AVRO-1170.patch
There was a mistake in the package name which I've now fixed
(org.apache.hadoop.mapreduce.TaskAttemptContext). I've also added a profile
that matches when you specify '-Dhadoop.version=1', since in the previous patch
this caused neither the hadoop1 nor the hadoop2 profile to match, which caused
a compilation error.
You need to do a 'mvn clean' before running the tests for a different Hadoop
version, otherwise the classes are not recompiled against the new Hadoop
classes and you get an IncompatibleClassChangeError. Thus:
{noformat}
mvn clean test -Dtest=TestAvroMultipleOutputs -Dhadoop.version=1
mvn clean test -Dtest=TestAvroMultipleOutputs -Dhadoop.version=2
{noformat}
> Avro's new mapreduce APIs don't work with Hadoop 2
