> When reading a parquet file using spark 1.3.0 lots of warnings are printed in the log:
> {noformat}
> WARNING: parquet.hadoop.ParquetRecordReader: Can not initialize counter due to context is not a instance of TaskInputOutputContext, but is org.apache.hadoop.mapreduce.task.TaskAttemptContextImpl
> {noformat}
> I have checked the source of ParquetRecordReader and found that while it checks for context to be TaskInputOutputContext it seems to never actually rely on this fact.
