      Description

      Attempting to store data into a Parquet table via HCatalog (using Pig) fails. Based on the code, it appears that org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat.getRecordWriter() is unimplemented.

      To duplicate:

      Hive:

      create table parquet_input_test stored as parquet as with x as (select test as value) select * from x;
      create table parquet_output_test (value int) stored as parquet;
      

      Pig:

      A = LOAD 'parquet_input_test' USING org.apache.hive.hcatalog.pig.HCatLoader();
      STORE A INTO 'parquet_output_test' USING org.apache.hive.hcatalog.pig.HCatStorer();
      

      Result:

      java.lang.RuntimeException: Should never be used
