>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: data-node
>    Affects Versions: 0.23.0, 0.24.0
>            Reporter: Steve Loughran
>            Assignee: Steve Loughran
>            Priority: Trivial

> Before starting HDFS-2472 I want to clean up the code in UnderReplicatedBlocks slightly
> # use constants for all the string levels
> # change the {{getUnderReplicatedBlockCount()}} method so that it works even if the corrupted block list is not the last queue
> # improve the javadocs
> # add some more curly braces and spaces to follow the style guidelines better
> This is a trivial change as behaviour will not change at all. If committed it will go into trunk and 0.23 so that patches between the two versions are easy to apply
