----------------------------------
[~Wencong Liu] Cool, really appreciated. The code is in
`HiveSourceFileEnumerator#enumerateSplits`, in where it will try to get all
splits for the hive table at once.
If you have any other problem, please let me know.

> Project: Flink
> Issue Type: Sub-task
> Components: Connectors / Hive
> Affects Versions: 1.16.0
> Reporter: luoyuxia
> Priority: Major
>
> Currently, when read hive source in batch mode, it'll first enumerate all
> split for the hive table. But when the table is large, the split will be too
> many which may well cause OOM. Some commuity users has also reported this
> problem.
> We need to optimize the logic for enumerating splits for hive table source to
> avoid potential OOM.
