   Yes. There are lots of change sinse your PR. `setSplitInfos` method is 
removed from the `SubstraitContext`. If we want to still follow that way, we 
need to bing it back or add separate property for this.
   And `getSplitInfos` is an expensive call, we should avoid to use it in 
validation. Instead we retrieve the first root path for validation here.
   And looks all file related validation is kept in the method 
`supportFileFormatRead`, file format, schema, etc. So we put the check here 
also.
   Last, `FakeParentPathFileSystem` doesn't work as expected in my local UT 
runs, mockfs:// is not supported by local file system. so I think a separate 
JNI wrapper API is needd for UT.
   Hee are the differences in my mind, please le me know is this makes sense to 
you, @PHILO-HE  and @wForget , thanks.
