Description

If I have the following JSON input:

{ "a" : [

{ "x": [[1], [2], [3]], "y": "abc"}

,

{ "x": [[5], [6], [7]], "y": "ABC"}

] }
{ "a" : [

{ "x": [[10], [20], [30]], "y": "abc2"}

,

{ "x": [[50], [60], [70]], "y": "ABC2"}

] }

For this query:

select t.a[1].x from dfs.`/Users/jni/work/data/json/input.json` t;

Drill will complain with compile error in run-time generated code:

Line 49, Column 34: No applicable constructor/method found for actual parameters "org.apache.drill.exec.vector.complex.writer.BaseWriter$ListWriter"; candidates are: "public abstract void org.apache.drill.exec.vector.complex.reader.TinyIntReader.copyAsValue(org.apache.drill.exec.vector.complex.writer.TinyIntWriter)",
