>            Reporter: Ying Zheng
>            Assignee: Ying Zheng
> Getting NoSuchMethodError (see below) when listing instances in different hadoop settings
due to the incompatibility with lower-version commons-lang jars. Changed to use isNotEmpty
as a workaround. Will investigate to see how to safely use this new api introduced in commons-lang-3.4.
