Subject [jira] [Commented] (HIVE-9242) Many places in CBO code eat exceptions
Date Fri, 02 Jan 2015 03:44:13 GMT

    [ https://issues.apache.org/jira/browse/HIVE-9242?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14262743#comment-14262743

Laljo John Pullokkaran commented on HIVE-9242:
----------------------------------------------

[~brocknoland] In this specific case exception is caught and thrown up as runtime exception.
I am guessing thats what you mean by CBO eating exceptions.

HiveException gets propagated through Calcite as a runtime exception; Without changing a lot
of plumbing in Calcite it would be difficult to explicitly throw HiveException.

This is not acceptable. Example:
