> Optimize split calculation time
> -------------------------------
>
> Key: HIVE-7052
> URL: https://issues.apache.org/jira/browse/HIVE-7052
> Project: Hive
> Issue Type: Bug
> Environment: hive + tez
> Reporter: Rajesh Balamohan
> Assignee: Rajesh Balamohan
> Labels: performance
> Attachments: HIVE-7052-profiler-1.png, HIVE-7052-profiler-2.png,

>
>
> When running a TPC-DS query (query_27), significant amount of time was spent
> in split computation on a dataset of size 200 GB (ORC format).
> Profiling revealed that,
> 1. Lot of time was spent in Config's subtitutevar (regex) in
> HiveInputFormat.getSplits() method.
> 2. FileSystem was created repeatedly in OrcInputFormat.generateSplitsInfo().
> I will attach the profiler snapshots soon.
