> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.4.0
> Environment: HBase 0.98.6-cdh5.3.0
> jdk1.7.0_67 x64
> CentOS release 6.4 (2.6.32-358.el6.x86_64)
> Reporter: Mykola Komarnytskyy
> Assignee: James Taylor
> Fix For: 4.5.0

> Steps to reproduce:
> 1. Create a table:
> CREATE TABLE mytable (id BIGINT not null PRIMARY KEY, timestamp BIGINT,
> log_message varchar) IMMUTABLE_ROWS=true, SALT_BUCKETS=16;
> 2. Create two indexes:
> CREATE INDEX mytable_index_search ON mytable(timestamp,id) INCLUDE
> (log_message) SALT_BUCKETS=16;
> CREATE INDEX mytable_index_search_desc ON mytable(timestamp DESC,id DESC)
> INCLUDE (log_message) SALT_BUCKETS=16;
> 3. Upsert values:
> UPSERT INTO mytable VALUES(1, 1434983826018, 'message1');
> UPSERT INTO mytable VALUES(2, 1434983826100, 'message2');
> UPSERT INTO mytable VALUES(3, 1434983826101, 'message3');
> UPSERT INTO mytable VALUES(4, 1434983826202, 'message4');
> 4. Sort DESC by timestamp:
> select timestamp,id,log_message from mytable ORDER BY timestamp DESC;
> Failure: data is sorted incorrectly. In case when we have two longs which
> are different only by last two digits (e.g. 1434983826155, 1434983826100)
> and one of the long ends with '00' we receive incorrect order.
> Sorting result:
> 1434983826202
> 1434983826100
> 1434983826101
> 1434983826018
