Subject [jira] [Updated] (HIVE-12543) Disable Hive ConstantPropagate optimizer when CBO has optimized the plan
Date Tue, 12 Jan 2016 12:37:39 GMT

     [ https://issues.apache.org/jira/browse/HIVE-12543?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jesus Camacho Rodriguez updated HIVE-12543:
-------------------------------------------
    Attachment: HIVE-12543.patch

Uploaded a patch that combines the work in HIVE-12478 with disabling ConstantPropagate. This
will give us a first idea of what is currently missing on the Calcite site wrt Hive optimizer,
and what would be needed in a simplified version of ConstantPropagate optimizer.
