     [ https://issues.apache.org/jira/browse/FLINK-3735?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vasia Kalavri reopened FLINK-3735:
----------------------------------

Even though the rule is supposed to covert all unions, we can still add an extra check in the {{DataSetUnionRule}} to be fully covered.

> The Table API currently only supports union all and embedded SQL queries translate both union and union all to union all. We should only generate a valid plan for union all.
