> When analyzing code coverage in Hadoop Core, we noticed that some coverage gaps are caused
by the way the coverage calculation is done currently. More specifically, right now coverage
can not be calculated for the whole Core at once, but can only be calculated separately for
top level modules like common-project, hadoop-hdfs-project etc. 
> At the same time, some code in particular modules is tested by tests in other modules
of Core. For example, "org.apache.hadoop.fs" from hadoop-common-project/hadoop-common is not
covered there but it's covered by tests under hadoop-hdfs-project.
> To enable calculation of "cumulative" code coverage it's needed to move Clover profile
definition up one level, from hadoop-project/pom.xml to the top level pom.xml (hadoop-main).
> Patch both for 0.23 and 2.x will be attached shortly.
