> The java.lang.NumberFormatException will throw with following reproduce:
> set hive.cbo.enable=false;
> CREATE TABLE `paqtest`(
> `c1` int,
> `s1` string,
> `s2` string,
> `bn1` bigint)
> ROW FORMAT SERDE
> 'org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe'
> STORED AS INPUTFORMAT
> 'org.apache.hadoop.hive.ql.io.parquet.MapredParquetInputFormat'
> OUTPUTFORMAT
> 'org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat';
> insert into paqtest values (58, '', 'ABC', 0);
> SELECT
> 'PM' AS cy,
> c1,
> NULL AS iused,
> NULL AS itp,
> s2,
> NULL AS cvg,
> NULL AS acavg,
> sum(bn1) AS cca
> FROM paqtest
> WHERE (s1 IS NULL OR length(s1) = 0)
> GROUP BY 'Pricing mismatch', c1, NULL, NULL, s2, NULL, NULL;
> The stack like following:
> java.lang.NumberFormatException: ABC
> GroupByOperator.process(Object, int) line: 773	
> ExecReducer.reduce(Object, Iterator, OutputCollector, Reporter) line: 236	
> ReduceTask.runOldReducer(JobConf, TaskUmbilicalProtocol, TaskReporter, RawKeyValueIterator, RawComparator<INKEY>, Class<INKEY>, Class<INVALUE>) line: 444	
> ReduceTask.run(JobConf, TaskUmbilicalProtocol) line: 392	
> LocalJobRunner$Job$ReduceTaskRunnable.run() line: 319	
> Executors$RunnableAdapter<T>.call() line: 471	
> It works fine when hive.cbo.enable = true
