> I am building Cassandra 2.2.3 on BigEndian System. Cassandra builds successfully. However
there are quite a few test case failures. One of the failing test case is LegacySSTableTest.
This test case reads the file test\data\legacy-sstables\jb\Keyspace1\Keyspace1-Standard1-jb-0-Summary.db
> Are these existing test data files, specific to Little Endian systems?
> I have observed differences in values read on a LE Vs BE systems.
> I use the following command to run the test case. ant test -Dtest.name=LegacySSTableTest
> I get the following error:
> [junit] ------------- Standard Error -----------------
> [junit] Failed to read jb
> [junit] ------------- ---------------- ---------------
