             Summary: The number of Offline Regions is wrong after restoring a snapshot.
                 Key: HBASE-19850
                 URL: https://issues.apache.org/jira/browse/HBASE-19850
             Project: HBase
          Issue Type: Bug
          Components: snapshots
            Reporter: Toshihiro Suzuki
             Fix For: 1.5.0
         Attachments: The number of Offline Regions.png

Steps to reproduce are as follows:

1. Create a table

{code}

create "test", "cf"

{code}

2. Take a snapshot for the table

{code}

snapshot "test", "snap"

{code}

3. Load data to the table

{code}

(0...2000).each\{|i| put "test", "row#{i}", "cf:col", "val"}

{code}

4. Split regions of the table

{code}

split "test"

{code}

5. Restore the table from the snapshot

 

{code}

disable "test"
restore_snapshot "snap"
enable "test"

{code}

 

The number of Offline Regions is as follows:

!The number of Offline Regions.png!

The number of Offline Regions should be zero.

It seems like when regions are removed by restoring a snapshot, the number of Offline Regions becomes wrong.
