> The private native method names and signatures in {{NativeCrc32}} were changed in HDFS-6561
... as a result hadoop-common-2.4 JARs get unsatisifed link errors when they try to perform
checksums. 
> This essentially stops Hadoop 2.4 applications running on Hadoop 2.6 unless rebuilt and
repackaged with the hadoop- 2.6 JARs
