Teng Qiu commented on SPARK-2443:
---------------------------------
Hi, how can you access parquet table using HiveContext / hql in spark? i tried
to add parquet-hive jar or parquet-hive-bundle jar in driver-class-path and
spark.executor.extraClassPath, but it doesn't work. CDH5.0.2, hive 0.12.0-cdh5
Thanks
