>                 URL: https://issues.apache.org/jira/browse/HADOOP-11064
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: native
>    Affects Versions: 2.6.0
>         Environment: Hadoop 2.6 cluster, trying to run code containing hadoop 2.4 JARs
>            Reporter: Steve Loughran
>            Assignee: Colin Patrick McCabe
>            Priority: Blocker
>         Attachments: HADOOP-11064.001.patch, HADOOP-11064.002.patch, HADOOP-11064.003.patch, HADOOP-11064.004.patch, HADOOP-11064.005.patch, HADOOP-11064.006.patch

>
> 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
