[jira] [Updated] (PARQUET-132) AvroParquetInputFormat should use a
parameterized type
[ https://issues.apache.org/jira/browse/PARQUET-132?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ryan Blue updated PARQUET-132:
------------------------------
Description:
The {{AvroParquetInputFormat}} currently extends {{ParquetInputFormat<IndexedRecord>}}, which works for regular MR cases. But Spark's {{hadoopRDD}} and [{{newAPIHadoopRDD}}|https://people.apache.org/~pwendell/spark-1.1.0-rc3-docs/api/java/org/apache/spark/SparkContext.html#newAPIHadoopRDD(org.apache.hadoop.conf.Configuration, java.lang.Class, java.lang.Class, java.lang.Class)] methods (correctly) create a RDD with the types from the InputFormat. This means that the RDD always uses {{IndexedRecord}} rather than the correct type.
The {{AvroParquetInputFormat}} should be {{AvroParquetInputFormat<T extends IndexedRecord> extends ParquetInputFormat<T>}}
