------------------------------
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?
