Subject [jira] [Updated] (HIVE-11151) Calcite transitive predicate inference rule should pay attention to its input rel type
Date Wed, 01 Jul 2015 15:19:05 GMT

     [ https://issues.apache.org/jira/browse/HIVE-11151?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ashutosh Chauhan updated HIVE-11151:
------------------------------------
    Attachment: HIVE-11151.4.patch

[~jcamachorodriguez] That check seems to be already present in that rule.
{code}
  RelDataType keyType = input.getRowType().getFieldList().get(pos).getType();
        // Nothing to do if key cannot be null
        if (!keyType.isNullable()) {
          continue;
        }
{code}

Or are you thinking of something else?
