code when it evaluates an expression returning a repeated list.
Jinfeng Ni created DRILL-1258:
---------------------------------
Summary: Drill hit compile error in generated code when it evaluates an expression returning a repeated list.
Key: DRILL-1258
URL: https://issues.apache.org/jira/browse/DRILL-1258
Project: Apache Drill
Issue Type: Bug
Reporter: Jinfeng Ni
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)",
