Description
Given the following JSON input data:
{ "a":[{"b": [["str1","str2"], ["str3", "str4"]]}] } { "a":[{"b": [["str10","str20"], ["str30", "str40"]]}] }
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:
select t.a[0].b[0] from dfs.`/Users/jni/work/data/json/samplejson.json` t;
Query failed: Failure while running fragment., You tried to read a [CopyAsValueVarChar] type when you are using a field reader of type [SingleLikeRepeatedMapReaderImpl]. [ d655b148-5c0e-4293-8472-8ee93d6df801 on adminisorsmbp53:31010 ]
