> Noticed that some of the Cassandra tests are failing on big endian 
> architectures (s390x). Please find the attached code patch which corrects the 
> data handling for big endian architecture. It also corrects the byte ordering 
> when dealing with sun.misc.Unsafe methods. After the patch following tests 
> are passing for s390x which were failing earlier:
> TTLTest
> ScrubTest
> LegacySSTableTest
> SSTableExportSchemaLoadingTest
> SSTableMetadataViewerTest
> StandaloneUpgraderOnSStablesTest
> StandaloneVerifierOnSSTablesTest
> The code change ensures that Cassandra for little endian architectures remain 
> unaffected.
