             Summary: Writes to parquet tables via HCatalog fail with "java.lang.RuntimeException: Should never be used".
                 Key: HIVE-7502
                 URL: https://issues.apache.org/jira/browse/HIVE-7502
             Project: Hive
          Issue Type: Bug
          Components: HCatalog
            Reporter: Craig Condit


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:
{noformat}
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;
{noformat}

Pig:
{noformat}
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();
{noformat}

Result:
{noformat}
