Kadir Ozdemir updated PHOENIX-6854:
-----------------------------------
Description:
With an index hint, global indexes can be used for queries with uncovered
columns. However, when the data table is salted, Phoenix does not project the
columns correctly for queries with uncovered columns, and thus the result set
returns wrong columns. For example, the following select statement returns 'b'
instead of 'bcde'.
{code:java}
create table T1 (id varchar not null primary key, val1 varchar, val2 varchar,
val3 varchar) SALT_BUCKETS=4;
upsert into T1 values ('b', 'bc', 'bcd', 'bcde');
create index I1 on T1 (val1) include (val2);
select /*+ INDEX(T1 I1)*/ val3 from T1 WHERE val1 = 'bc';
{code}
