>
> The CombineFileInputFormat class in org.apache.hadoop.mapred.lib (the old 
> API) has a couple of issues. These issues were addressed in the new API 
> (MAPREDUCE-1423), but the old class was not fixed.
> The main issue the JIRA refers to is a performance problem. However, IMO 
> there is a more serious problem which is a thread-safety issue (rackToNodes) 
> which was fixed alongside.
> What is the policy on addressing issues in the old API? Can we backport this 
> to the old class?
