---------------------------------
Summary: Drill fails when querying a nested array within a
repeated map.
Key: DRILL-1634
URL: https://issues.apache.org/jira/browse/DRILL-1634
Project: Apache Drill
Issue Type: Bug
Reporter: Jinfeng Ni
Assignee: Jinfeng Ni
Given the following JSON input data:
{code}
{ "a":[{"b": [["str1","str2"], ["str3", "str4"]]}] }
{ "a":[{"b": [["str10","str20"], ["str30", "str40"]]}] }
{code}
If we want to retrieve the first element in array b, which is the first element
in array a, using the following query, Drill will fail with error:
{code}
select t.a[0].b[0] from dfs.`/Users/jni/work/data/json/samplejson.json` t;
{code}
{code}
