Yin Huai created SPARK-18660:
--------------------------------
Summary: Parquet complains "Can not initialize counter due to context is not a instance of TaskInputOutputContext, but is org.apache.hadoop.mapreduce.task.TaskAttemptContextImpl "
Key: SPARK-18660
URL: https://issues.apache.org/jira/browse/SPARK-18660
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Yin Huai
Parquet record reader always complain "Can not initialize counter due to context is not a instance of TaskInputOutputContext, but is org.apache.hadoop.mapreduce.task.TaskAttemptContextImpl". Looks like we always create TaskAttemptContextImpl (https://github.com/apache/spark/blob/2f7461f31331cfc37f6cfa3586b7bbefb3af5547/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/parquet/ParquetFileFormat.scala#L368). But, Parquet wants to use TaskInputOutputContext, which is a subclass of TaskAttemptContextImpl.
