Xiaobing Zhou commented on HIVE-8115: ------------------------------------- LazyMap was commented as "LazyMap does not deal with the case of a NULL map. That is handled by the parent LazyObject.", so it'd better to output some warning message regarding empty key or pair in line 173 of LazyMap.parse(). > Hive select query hang when fields contain map > ---------------------------------------------- > > Key: HIVE-8115 > URL: https://issues.apache.org/jira/browse/HIVE-8115 > Project: Hive > Issue Type: Bug > Affects Versions: 0.13.0 > Reporter: Xiaobing Zhou > Assignee: Xiaobing Zhou > Fix For: 0.14.0 > > Attachments: createTable.hql, data > > > Attached the repro of the issue.
