Kosmos distributed file system (KFS) provides high performance combined with availability and reliability. It is intended to be used as the back-end storage infrastructure for data intensive apps such as search engines, data mining, grid computing, etc. KFS has been deployed in production settings on large clusters to manage multiple petabytes of storage. KFS is implemented in C++ using standard system components such as STL, boost libraries, AIO, log4cpp. KFS is integrated with Hadoop and Hypertable.

KFS upstream seems dead. Do you really want to maintain this package? Or switch to QFS, what you have mentioned in the specfile?
As a dependency for the Hadoop 2.x series, we would like to maintain KFS for a period of time and guide Hadoop upstream adoption towards QFS. QFS can be configured in as a pluggable and optimized replacement for KFS so we could develop and package that in parallel (spec and review TBD).

Looking at 2.0.5, it appears to be a testing only dependency (possibly for compatibility). It appears we may be able to prune the dependency entirely as we track forward progress a bit closer.
Update has been made to branch-2 stream to remove. ref: https://issues.apache.org/jira/browse/HADOOP-8886 I also verified it is no longer required for build and is removed. recommend CLOSE->WONTFIX IMHO, we should still pursue QFS support in the future as time permits.
