Review comment:
Is list files needed again ? It is costly in S3a/OBS. It is better to keep the list of data files and index files participated in rebuild in memory and clean up after rebuild without calling list files again.

Review comment:
Please test the scenario when
(1) the index files before rebuild is already queried and cached
(2) then rebuild and query are concurrent
in this scenario query will take the index file and go on query, but if the rebuild deletes it, then the file will be unavailable and either says exception or will result in null set.

Review comment:
this scenario is verified, during query if the rebuild finished before caching,then it should not be a problem, but if its already reading then it might fail, this is scenario in many cases, like merge index, index server, because we dont have lock mechanism in read right, so this should be ok
