----------------------------
Summary: Handle StringIndexOutOfBoundsException in
canCBOHandleAst() method.
Key: HIVE-26426
URL: https://issues.apache.org/jira/browse/HIVE-26426
Project: Hive
Issue Type: Bug
Components: HiveServer2
Reporter: Abhay
Assignee: Abhay
The call to canHandleQbForCbo() can result in an
StringIndexOutOfBoundsException. The assumption in the code is that the msg can
only be null and we handle that but the msg can also be an empty string if the
*verbose* is set to false. This can happen if INFO Logging is not enabled. We
need to handle that case.
