Date Sat, 25 Aug 2018 21:34:00 GMT
Gardella Juan Pablo created PHOENIX-4869:
--------------------------------------------

             Summary: Empty row when using OFFSET + LIMIT
                 Key: PHOENIX-4869
                 URL: https://issues.apache.org/jira/browse/PHOENIX-4869
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.7.0
            Reporter: Gardella Juan Pablo
         Attachments: empty_row.png, no_results.png

I'm using [Phoenix shipped |https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.3/bk_release-notes/content/patch_phoenix.html]at
[HDP 2.6.3|https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.3/index.html]. I have a
table defined as:
{code:sql}
 
create table test (
   id VARCHAR not null primary key,
   json VARCHAR
)
{code}
It has 2559774 rows. If I execute the following query, it returns a row with a null value.
{code:sql}
select * from
(
   SELECT ID
   FROM test
   LIMIT 100000 OFFSET 100000
)
where ID is null
{code}
 
 I was reviewing the git logs and I didn't see any commit related to that[1]. Notice the query
for OFFSET and LIMIT lowers than 10000 does not fail. I've attached a capture of the query
results.

Notice if I execute SELECT ID FROM test WHERE ID IS NULL returns an empty result as expected.
