             Summary: NullPointerException when using an index and a char array
                 Key: PHOENIX-2304
                 URL: https://issues.apache.org/jira/browse/PHOENIX-2304
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.5.2
            Reporter: Julian Jaffe


An NPE occurs when Phoenix attempts to retrieve a char array from an index. 
Retrieving other columns in the table is unaffected. Example below: 

{code:sql}
0: jdbc:phoenix:xxxxxx> CREATE TABLE IF NOT EXISTS TEST.TEST("testInt" INTEGER, 
"testCharArray" CHAR(3)[], CONSTRAINT "test_pk" PRIMARY KEY("testInt")) 
DEFAULT_COLUMN_FAMILY='T';
No rows affected (2.223 seconds)
0: jdbc:phoenix:xxxxxx> UPSERT INTO TEST.TEST VALUES (5, ARRAY['aaa', 'bbb']);
1 row affected (0.165 seconds)
0: jdbc:phoenix:xxxxxx> SELECT "testCharArray" FROM TEST.TEST;
+---------------+
| testCharArray |
+---------------+
| ['aaa', 'bbb'] |
+---------------+
1 row selected (0.183 seconds)
0: jdbc:phoenix:xxxxxx> CREATE INDEX IF NOT EXISTS TEST_INDEX ON TEST.TEST 
("testInt") INCLUDE ("testCharArray");
1 row affected (10.331 seconds)
0: jdbc:phoenix:xxxxxx> EXPLAIN SELECT "testCharArray" FROM TEST.TEST;
+------------------------------------------+
|                   PLAN                   |
+------------------------------------------+

+------------------------------------------+
1 row selected (0.173 seconds)
0: jdbc:phoenix:xxxxxx> SELECT "testCharArray" FROM TEST.TEST;
+---------------+
| testCharArray |
+---------------+
| ['aaa', 'bbb'] |
+---------------+
1 row selected (0.475 seconds)
0: jdbc:phoenix:xxxxxx> EXPLAIN SELECT /*+ INDEX(TEST.TEST TEST_INDEX)*/ 
"testCharArray" FROM TEST.TEST;
+------------------------------------------+
|                   PLAN                   |
+------------------------------------------+
| CLIENT 1-CHUNK PARALLEL 1-WAY FULL SCAN OVER TEST.TEST_INDEX |
+------------------------------------------+
1 row selected (0.186 seconds)
0: jdbc:phoenix:xxxxxx> SELECT /*+ INDEX(TEST.TEST TEST_INDEX)*/ 
"testCharArray" FROM TEST.TEST;
+------------------------------------------+
|              testCharArray               |
+------------------------------------------+
