[jira] [Updated] (HBASE-19893) restore_snapshot is broken in master
branch
[ https://issues.apache.org/jira/browse/HBASE-19893?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Toshihiro Suzuki updated HBASE-19893:
-------------------------------------
Description:
When I was investigating HBASE-19850, I found restore_snapshot didn't work in master branch.
Steps to reproduce are as follows:
1. Create a table
{code:java}
create "test", "cf"
{code}
2. Load data (2000 rows) to the table
{code:java}
(0...2000).each{|i| put "test", "row#{i}", "cf:col", "val"}
{code}
3. Split the table
{code:java}
split "test"
{code}
4. Take a snapshot
{code:java}
snapshot "test", "snap"
{code}
5. Load more data (2000 rows) to the table and split the table agin
{code:java}
(2000...4000).each{|i| put "test", "row#{i}", "cf:col", "val"}
split "test"
{code}
6. Restore the table from the snapshot
{code:java}
disable "test"
restore_snapshot "snap"
enable "test"
{code}
7. Scan the table
{code:java}
scan "test"
{code}
However, this scan returns only 244 rows (it should return 2000 rows) like the following:
{code:java}
hbase(main):038:0> scan "test"
ROW COLUMN+CELL
row78 column=cf:col, timestamp=1517298307049, value=val
....
row999 column=cf:col, timestamp=1517298307608, value=val
244 row(s)
Took 0.1500 seconds
{code}
Also, the restored table should have 2 online regions but it has 3 online regions.
