[jira] [Updated] (HIVE-8064) CBO: decimal support is broken for some corner cases

     [ https://issues.apache.org/jira/browse/HIVE-8064?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sergey Shelukhin updated HIVE-8064:
-----------------------------------
    Attachment: HIVE-8064.patch

This patch works around some assert in Optiq where Hive supports wider decimals than Optiq; and also disables CBO for invalid decimals like 1E99 (for the reason stated in comment - it seems like it would be hard to fix for little benefit)
