Subject [jira] [Updated] (DRILL-5523) Revert if condition in UnionAllRecordBatch changed in DRILL-5419
Date Thu, 18 May 2017 12:15:04 GMT

     [ https://issues.apache.org/jira/browse/DRILL-5523?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arina Ielchiieva updated DRILL-5523:
------------------------------------
    Description: 
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 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.
