> StackOverflowError in reverse scan
> ----------------------------------
>
> Key: HBASE-14155
> URL: https://issues.apache.org/jira/browse/HBASE-14155
> Project: HBase
> Issue Type: Bug
> Components: regionserver, Scanners
> Affects Versions: 1.1.0
> Reporter: James Taylor
> Assignee: ramkrishna.s.vasudevan
> Priority: Critical
> Labels: Phoenix
> Attachments: 14155-branch-1.txt, HBASE-14155.patch,

>
> 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;
