> Issue Type: Bug
> Components: Build, Input/Output, Spark Core
> Affects Versions: 0.9.1, 1.0.0, 1.1.0
> Environment: hadoop2, hadoop-2.4.0, HDP-2.1

> The spark assembly contains the artifact "org.apache.avro:avro-mapred" as a dependency of "org.spark-project.hive:hive-serde".
> The avro-mapred package provides a hadoop FileInputFormat to read and write avro files. There are two versions of this package, distinguished by a classifier. avro-mapred for the new Hadoop API uses the classifier "hadoop2". avro-mapred for the old Hadoop API uses no classifier.
> E.g. when reading avro files using

> sc.newAPIHadoopFile[AvroKey[SomeClass]],NullWritable,AvroKeyInputFormat[SomeClass]]("hdfs://path/to/file.avro")

> This error usually is a hint that there was a mix up of the old and the new Hadoop API. As a work-around, if avro-mapred for hadoop2 is "forced" to appear before the version that is bundled with Spark, reading avro files works fine.
> Also, if Spark is built using avro-mapred for hadoop2, it works fine as well.
