Ches Martin commented on HIVE-7502:
-----------------------------------
This was probably resolved by HIVE-8838—linked to this issue already—which was
backported from Hive 3 to 2 by HIVE-22249.
> 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
> Affects Versions: 0.13.1
> Reporter: Craig Condit
> Priority: Major
>
> 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}
> java.lang.RuntimeException: Should never be used
