Jimmy Xiang commented on HIVE-9367:
-----------------------------------
So far, I don't find such a subclass/caller. Without overriding that method, we
may need to enhance MR code a little, for example, adding a new API/setting,
which is not practical. Probably for now, overriding the method is what we can
do. Thanks.

> [~lirui] found out that we spent quite some time on
> CombineFileInputFormatShim#getDirIndices. Looked into it and it seems to me
> we should be able to get rid of this method completely if we can enhance
> CombineFileInputFormatShim a little.
