> LLAP: improve data tags for cache view to not be based on paths
> ---------------------------------------------------------------
>
> 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.
