Some of the C and C++ files are missing Apache License headers.
I just merged this to 0.14.4.
Might as well fix in 0.14.4.
I've merged this into branch-0.15.0 since I needed to merge subsequent patches (e.g. HADOOP-2169).
Integrated in Hadoop-Nightly #290 (See http://lucene.zones.apache.org:8080/hudson/job/Hadoop-Nightly/290/)
I've committed this to head, but I'll hold off on copying it to the 0.15 branch until after the 0.15.0rc1 vote passes or fails.
