> Unsupported FS operations should throw UnsupportedOperationException
> --------------------------------------------------------------------
>
> Key: HADOOP-12726
> URL: https://issues.apache.org/jira/browse/HADOOP-12726
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs
> Affects Versions: 2.7.1
> Reporter: Daniel Templeton
> Assignee: Daniel Templeton
> Attachments: HADOOP-12726.001.patch
>
>
> In the {{FileSystem}} implementation classes, unsupported operations throw
> {{new IOException("Not supported")}}, which makes it needlessly difficult to
> distinguish an actual error from an unsupported operation. They should
> instead throw {{new UnsupportedOperationException()}}.
> It's possible that this anti-idiom is used elsewhere in the code base. This
> JIRA should include finding and cleaning up those instances as well.
