------------------------------

             Summary: repeated_count does not work for multi-level array data type?
                 Key: DRILL-1650
                 URL: https://issues.apache.org/jira/browse/DRILL-1650
             Project: Apache Drill
          Issue Type: Bug
          Components: Functions - Drill
    Affects Versions: 0.6.0
            Reporter: Hao Zhu


1. "n1.json" is :
{code}
{"test":[1,2,3,4,4,5]}
{code}

Then the function works fine:
{code}
0: jdbc:drill:> select repeated_count(t.test) from `n1.json` as t;
+------------+
|   EXPR$0   |
+------------+
| 6          |
+------------+
{code}

2. However if the json has 2-level or more arrays:
{code}
{"test":[[1,2,3,4,5,6]]}
{code}

The function failed:
{code}
0: jdbc:drill:> select t.test[0][0],t.test[0][1] from `n4.json` as t;
+------------+------------+
|   EXPR$0   |   EXPR$1   |
+------------+------------+
| 1          | 2          |
+------------+------------+
1 row selected (0.126 seconds)
0: jdbc:drill:> select repeated_count(t.test[0]) from `n4.json` as t;
Query failed: Screen received stop request sent. Line 54, Column 22: "end" is neither a method, a field, nor a member class of "org.apache.drill.exec.vector.complex.reader.FieldReader" [11c5ff5b-c00f-4754-9bda-c3bec9471f72]

Error: exception while executing query: Failure while trying to get next result batch. (state=,code=0)
{code}

Am I missing something or is this a bug?
