Sure .. the data is brought over into the EMR (5.0.0) HDFS cluster via sqoop. Once there, I issue the following commands in Hive (2.1.0) to store it in S3 -

CREATE EXTERNAL TABLE <s3_tablename> (
   col1 bigint,
   col2 int,
   col3 string,
   ....
)
PARTITIONED BY (col8 int)
STORED AS PARQUET
LOCATION 's3_table_dir'

INSERT into <s3_tablename>
SELECT col1,col2,.... FROM <hdfs_tablename>

> If I try to inner-join two dataframes which originated from the same initial dataframe that was loaded using spark.sql() call, it results in an error -
> // reading from Hive .. the data is stored in Parquet format in Amazon S3
> val d1 = spark.sql("select * from <hivetable>")  
> val df1 = d1.groupBy("key1","key2")
>           .agg(avg("totalprice").as("avgtotalprice"))
> val df2 = d1.groupBy("key1","key2")
>           .agg(avg("itemcount").as("avgqty")) 
> df1.join(df2, Seq("key1","key2")) gives error -
> org.apache.spark.sql.AnalysisException: using columns ['key1,'key2] can 
> not be resolved given input columns: [key1, key2, avgtotalprice, avgqty];
> If the same Dataframe is initialized via spark.read.parquet(), the above code works. This same code above worked with Spark 1.6.2
