Subject [jira] [Created] (HBASE-14155) StackOverflowError in reverse scan
Date Sat, 25 Jul 2015 18:15:04 GMT
James Taylor created HBASE-14155:
------------------------------------

             Summary: StackOverflowError in reverse scan
                 Key: HBASE-14155
                 URL: https://issues.apache.org/jira/browse/HBASE-14155
             Project: HBase
          Issue Type: Bug
    Affects Versions: 1.1.0
            Reporter: James Taylor


A stack overflow may occur when a reverse scan is done. To reproduce (on a Mac), use the following
steps:
- Download the Phoenix 4.5.0 RC here: https://dist.apache.org/repos/dist/dev/phoenix/phoenix-4.5.0-HBase-1.1-rc0/bin/
- Copy the phoenix-4.5.0-HBase-1.1-server.jar into the HBase lib directory (removing any earlier
Phoenix version if there was one installed)
- Stop and restart HBase
- From the bin directory of the Phoenix binary distribution, start sqlline like this: ./sqlline.py
localhost
- Create a new table and populate it like this:
{code}
create table desctest (k varchar primary key desc);
upsert into desctest values ('a');
upsert into desctest values ('ab');
upsert into desctest values ('b');
{code}
- Note that the following query works fine at this point:
{code}
select * from desctest order by k;
+------------------------------------------+
|                    K                     |
+------------------------------------------+
| a                                        |
| ab                                       |
| b                                        |
+------------------------------------------+
{code}
- Stop and start HBase
- Rerun the above query again and you'll get  a StackOverflowError at StoreFileScanner.seekToPreviousRow()
{code}
select * from desctest order by k;

{code}

I've attempted to reproduce this in a standalone HBase unit test, but have not been able to
(but I'll attach my attempt which mimics what Phoenix is doing).
