> Compression.java different compressions load system classpath differently

> I stumbled upon this issue when testing Snappy compression on hbase tables
> with a webserver.
> On the webserver the system classpath of the server JVM did not include the
> path to hadoop-common.jar and since it is hardcoded to only retrieve the
> system classpath it ran into a NoClassDefFoundException using hte following
> call ClassLoader.getSystemClassLoader()
> However LZ4 compression works using this private method
> getClassLoaderForCodec() which attempts to load the threads classpath first
> and the system classpath last.
> I propose to change all the ClassLoader.getSystemClassLoader() calls to
> getClassLoaderForCodec() to allow for consistent behavior in loading
> compression classes and to also make it easier for users to make sure they do
> not run into RuntimeExceptions.
