The code is rather trivial:
{code}
val sc = new SparkContext(sparkConf)
val sqlContext = new org.apache.spark.sql.SQLContext(sc)
val tweets = sqlContext.jsonFile(path).cache()
tweets.saveAsParquetFile("tweets.parquet")

> Spark assembly for new hadoop API (hadoop 2) contains avro-mapred for hadoop

> Key: SPARK-3039
> URL: https://issues.apache.org/jira/browse/SPARK-3039
> Project: Spark
> 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
> Reporter: Bertrand Bossy

> 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
> {code}
> sc.newAPIHadoopFile[AvroKey[SomeClass]],NullWritable,AvroKeyInputFormat[SomeClass]]("hdfs://path/to/file.avro")
> {code}
> The following error occurs:

> 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.
