---------------------------------------
Assignee: Volodymyr Vysotskyi (was: Arina Ielchiieva)
> IndexOutOfBoundsException during union all for map types
> --------------------------------------------------------
>
> Key: DRILL-5521
> URL: https://issues.apache.org/jira/browse/DRILL-5521
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.11.0
> Reporter: Arina Ielchiieva
> Assignee: Volodymyr Vysotskyi
> Fix For: Future
>
>
> In DRILL-5419 introduced some changes in UnionAllRecordBatch.
> One change allowed to transfer data directly if column name is the same.
> This part of code existed before but was not executed since if condition was
> always returning false:
> {noformat}
> if(outputFields.get(index).getPath().equals(inputPath)) {
> {noformat}
> But fixing this condition lead to the following error
> Change in code:
> {noformat}
> if (outputFields.get(index).getPath().equals(inputPath.getAsUnescapedPath()))
> {
> {noformat}
> Data set:
> {noformat}
> cat missing-map.json
> {"rk": "a", "m": {"a":"1"}}
> {noformat}
> Query:
> {noformat}
> select kvgen(m) from (select m from dfs.`missing-map.json` union all select
> convert_from('{"a" : null}' ,'json') as m from (values(1)))
> {noformat}
> Error:
> {noformat}
