> TableSnapshotScanner fails on an already restored MOB table snapshot

> Key: HBASE-30368
> URL: https://issues.apache.org/jira/browse/HBASE-30368
> Project: HBase
> Issue Type: Bug
> Components: mob
> Reporter: Xiao Liu
> Assignee: Xiao Liu
> Priority: Major
> Fix For: 4.0.0-alpha-1, 2.7.0, 3.1.0, 3.0.1, 2.6.8

> h2. Problem
> HBASE-30365 fixed this issue for \{{TableSnapshotInputFormat}}, but
> \{{TableSnapshotScanner}} still includes the MOB pseudo-region when
> \{{snapshotAlreadyRestored=true}}. Since HBASE-30336 no regular region
> directory is created for this pseudo-region, scanning fails with:
> {noformat}
> java.io.IOException: Region directory does not exist:
> .../<mob-region-encoded-name>
> {noformat}
> This also affects \{{VerifyReplication}} when a MOB peer snapshot is used.
> h2. Fix
> Skip \{{MobUtils.isMobRegionInfo(hri)}} in
> \{{TableSnapshotScanner.isValidRegion}} and add a regression test.
