cdh3 client interoperable with apache hadoop server 0.20.xx?

we have a hadoop-core-0.20.2-cdh3u1.jar based java client. Would it be safe to work against a server (cluster) running apache distributed 0.20.xx? Or did cloudera break some apache APIs?

Thanks

probably a bad idea. Tried working with a client using hadoop-core version 0.20.203.0 against a server with cdh3u1 and got:

org.apache.hadoop.ipc.RPC$VersionMismatch: 
Protocol org.apache.hadoop.hdfs.protocol.ClientProtocol version mismatch. (client = 61, server = 63)

Didn't try the other way around...
