Date Tue, 11 Aug 2015 01:28:45 GMT

     [ https://issues.apache.org/jira/browse/PHOENIX-2137?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

James Taylor updated PHOENIX-2137:
----------------------------------
    Attachment: PHOENIX-2137_v2.patch

Final patch with more testing. Please review, [~samarthjain] - I'd like to get this into a
patch release very soon so we can put these descending row key bugs behind us.

> The following scenario is not working correctly:
> {code}
> create table t (k1 bigint not null, k2 decimal, constraint pk primary key (k1,k2 desc));
> upsert into t values(1,1.01);
> upsert into t values(2,1.001);
> select * from t where k2>1.0; -- No rows, but should be both rows
> select * from t where k1 in (1,2) and k2>1.0; -- Same problem
> {code}
> The following queries do return the correct results:
> {code}
> select * from t where k2>1.0001;
> select * from t where k1 in (1,2) and k2>1.0001;
> {code}
> Note also that without the DESC declaration of k2, everything works fine.
