Anoop Sam John commented on HBASE-18049:
----------------------------------------
A bug some where in the code makes this MOB data not found. The cell may be in
some other MOB file and we have an issue in the MOB ref cell read. A solution
to restore the state and data is to do a MOB major compaction right? May be we
should add that info the error log clearly.
> It is not necessary to re-open the region when MOB files cannot be found

> In HBASE-17712, we try to re-open the region when store files cannot be
> found. This is useful for store files in a region, but is not necessary when
> the MOB files cannot be found, because the store files in a region only
> contain the references to the MOB files and a re-open of a region doesn't
> help the lost MOB files.
> In this JIRA, we will directly throw DNRIOE only when the MOB files are not
> found in {{MobStoreScanner}} and {{ReversedMobStoreScanner}}. Other logics
> keep the same.
