Jeffrey Zhong commented on PHOENIX-1257:
----------------------------------------
Nice. Currently we run IT tests on window cluster so after the fix I can give a
try to see if build breaks. Without scn++; we see many random test failures.
> Strange behavior wirh "upsert into ... select from ..." with sequences
> ----------------------------------------------------------------------

> Key: PHOENIX-1257
> URL: https://issues.apache.org/jira/browse/PHOENIX-1257
> Project: Phoenix
> Issue Type: Bug
> Reporter: Lars Hofhansl
> Priority: Critical
> Attachments: 1257-WIP.txt, 1257-test.txt
>
>
> I have the following scenario:
> create sequence keys;
> create table X (pk unsigned_long primary key, val integer);
> upsert into x values (1,1);
> Followed by repeated:
> upsert into x select next value for keys, val from x;
> This works well until 2048 rows are inserted. The next
> upsert into x select next value for keys, val from x;
> That loops forever inserting more and more rows until it is stopped.
