Review comment:
This is a valid test, but I think the testMultipleInserts test for
inserts, and this is test for deletes. Maybe create its' own test method named
testDeleteOfInserts like testUpdateOfInserts?

> Since HIVE-23840 LLAP cache is used to retrieve the tail of the ORC bucket
> files in the delete deltas, but to use the cache the fileId must be
> determined, so one more FileSystem call is issued for each bucket.
> This fileId is already available during compilation in the AcidState
> calculation, we should serialise this to the OrcSplit, and remove the
> unnecessary FS calls.
> Furthermore instead of sending the SyntheticFileId directly, we should pass
> the attemptId instead of the standard path hash, this way the path and the
> SyntheticFileId. can be calculated, and it will work even, if the move free
> delete operations will be introduced.
