Anoop Sam John commented on HBASE-14155:
----------------------------------------
{code}
STATE tmp = previous;
previous = current;
current = tmp;
{code}
This was not enough? We need to specifically call setKey() again? Some thing
wrong in the overall flow then.. May be we need revisit this. Chances of
missing these kind of setters is more then..
> 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: HBASE-14155.patch, ReproReverseScanStackOverflow.java,
> ReproReverseScanStackOverflowCoprocessor.java
>
>
> 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;
