Allen Wittenauer commented on HADOOP-11064:
-------------------------------------------
bq. unfortunately afaik Java doesn't provide a way to specify a particular so
version dependency.
I keep thinking that System.load("/full/path/libname.so.1.2.3") worked. (We
should be able to figure out the full path by just processing java.library.path
manually or maybe reading hadoop.native.dir or whatever.)

> Key: HADOOP-11064
> 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
> Priority: Blocker
>
> 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
