---------------------------------
Component/s: Query Processor
> CombineFileInputFormat fails if mapred.job.tracker is set to local with a
> sub-query
> -----------------------------------------------------------------------------------

> Key: HIVE-2737
> URL: https://issues.apache.org/jira/browse/HIVE-2737
> Project: Hive
> Issue Type: Bug
> Components: Query Processor
> Affects Versions: 0.8.0
> Reporter: Esteban Gutierrez
>
> If the CombineFileInputFormat and mapred.job.tracker=local are used together,
> the CombineFileInputFormat throws a java.io.FileNotFoundException if the
> query statment contains a sub-query:
> {code}
> hive> select count(*) from (select count(*), a from hivetest2 group by a) x;
> Total MapReduce jobs = 2
> Launching Job 1 out of 2
> Number of reduce tasks not specified. Estimated from input data size: 1
> In order to change the average load for a reducer (in bytes):
> set hive.exec.reducers.bytes.per.reducer=<number>
> In order to limit the maximum number of reducers:
> set hive.exec.reducers.max=<number>
> In order to set a constant number of reducers:
> set mapred.reduce.tasks=<number>
> Execution log at:
