Arina Ielchiieva created DRILL-5523: ---------------------------------------
Summary: Revert if condition in UnionAllRecordBatch changed in DRILL-5419 Key: DRILL-5523 URL: https://issues.apache.org/jira/browse/DRILL-5523 Project: Apache Drill Issue Type: Bug Affects Versions: 1.11.0 Reporter: Arina Ielchiieva Assignee: Arina Ielchiieva Fix For: 1.11.0 If condition in UnionAllRecordBatch which was changed to correct one in DRILL-5419 but this change caused the regression (DRILL-5521). The root cause is not in change itself but rather in missing indication of child column in map types when it is null. There is a big project upcoming to re-working json reader implementation, including map types (DRILL-4824) which will fix the problem. So far reverting change to previous one so users won't see the regression till DRILL-4824 is merged. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
