[jira] [Commented] (HIVE-8657) CBO: inputddl5, udf_reverse tests fail

    [ https://issues.apache.org/jira/browse/HIVE-8657?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14189084#comment-14189084 ] 

Julian Hyde commented on HIVE-8657:
-----------------------------------

I suspect that the Hive-to-Calcite is generating a RexLiteral (possibly a SqlLiteral) for a character literal, and that that character literal contains Unicode (i.e. non-ASCII) characters. Fix might be to catch the exception and create the literal using unicode as the encoding.

Note that in a RexLiteral of type CHAR or VARCHAR, the value object must be of type NlsString, and that contains a Java string (in unicode as always), a java.nio.charset.Charset, and a SqlCollation.

It should be clearer what to do when we see the call-stack.
