Toshihiro Suzuki commented on HBASE-19893: ------------------------------------------ [~yuzhih...@gmail.com] I was able to reproduce this issue on branch-2 by following the steps. The revision is 7e7917ed6d99eae70ce40f1a498c022765a035c6. This may be the same root cause as HBASE-19850. Currently when restoring a snapshot, the states of AssignmentManager is not changed, but it looks like to me that we need to change it. > restore_snapshot is broken in master branch > ------------------------------------------- > > Key: HBASE-19893 > URL: https://issues.apache.org/jira/browse/HBASE-19893 > Project: HBase > Issue Type: Bug > Reporter: Toshihiro Suzuki > Assignee: Toshihiro Suzuki > Priority: Critical > > 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} > 8. 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. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
