> Key: HIVE-12847
> URL: https://issues.apache.org/jira/browse/HIVE-12847
> Project: Hive
> Issue Type: Improvement
> Components: File Formats, ORC
> Affects Versions: 1.2.1
> Reporter: Nemon Lou

>
> The size based footer cache can not control memory usage properly.
> Having seen a HiveServer2 hang due to ORC file footer cache taking up too
> much heap memory.
> A simple query like "select * from orc_table limit 1" can make HiveServer2
> hang.
> The input table has about 1000 ORC files and each ORC file owns about 2500
> stripes.
