java hdfs api protocol buffer exception

I'm running a java app using hadoop-2.0.5-alpha. My code looks like:

FileSystem fileSystem = FileSystem.get(conf);
Path path = new Path("/tmp/sample.txt");
System.out.println(fileSystem.exists(path));

But I get an exception

com.google.protobuf.InvalidProtocolBufferException: Message missing required fields: callId, status

I haven't been able to find much on what causes this error. Any thoughts?

It seems you are using hadoop-2.0.5-alpha in the client. But the sever version may be too low.

Type hadoop version to check the version.
