------------------------------------
Summary: It is not necessary to re-open the region when MOB files
cannot be found
Key: HBASE-18049
URL: https://issues.apache.org/jira/browse/HBASE-18049
Project: HBase
Issue Type: Bug
Components: Scanners
Reporter: Jingcheng Du
Assignee: Jingcheng Du
Fix For: 2.0.0
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.
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.
