> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 2.9.0, 3.0.0

> Assignee: Jim Brennan
> Priority: Major

>
> Before [HADOOP-13556], Configuration.getPropsWithPrefix() used the
> Configuration.get() method to get the value of the variables. After
> [HADOOP-13556], it now uses props.getProperty().
> The difference is that Configuration.get() does deprecation handling and more
> importantly variable substitution on the value. So if a property has a
> variable specified with ${variable_name}, it will no longer be expanded when
> retrieved via getPropsWithPrefix().
> Was this change in behavior intentional? I am using this function in the fix
> for [MAPREDUCE-7069], but we do want variable expansion to happen.
