@dhatchayani ...From my perspective I think this PR is not required. This
is a case when user deletes the dictionary and sort index file intentionally
from back end from the system and keeps only the dictionary meta file. But in
any case user should not be allowed to delete any of the carbon store files.
Therefore I think we should not handle this scenario.---
