>                 Key: HIVE-18936
>                 URL: https://issues.apache.org/jira/browse/HIVE-18936
>             Project: Hive
>          Issue Type: Bug
>            Reporter: Sergey Shelukhin
>            Priority: Major
>
> Due to Hive splits limitations (the only thing they have is file paths) the 
> database/table/partition tags for cache entries (see HIVE-16992) are 
> guesswork derived from file paths.
> We should improve them; in some cases where split code is in Hive (e.g. 
> OrcSplit) we can add information directly to the split.
> For others, we can consider passing information as part of JobConf or in some 
> other way. Hive execution already has path to partition mapping, so we may be 
> able to utilize that.
