HBase error: Server IPC version 8 cannot communicate with client version 4

I'm using hbase-0.94.9, I tried to follow the introductions from HBase online book, but I got the error:

org.apache.hadoop.hbase.master.HMasterCommandLine: Failed to start master
java.net.ConnectException: Call to localhost/127.0.0.1:8020 failed on connection exception: java.net.ConnectException

Then I found on the Web that I had to set up Hadoop first, I used start-dfs.sh in Hadoop 2.0.5-alpha but now I get this error, when I try to run start-hbase.sh:

2013-07-09 17:27:40,706 FATAL org.apache.hadoop.hbase.master.HMaster: Unhandled exception. Starting shutdown.
org.apache.hadoop.ipc.RemoteException: Server IPC version 8 cannot communicate with client version 4

You trying to use an HBase release that was built against Hadoop 1.0.x with hadoop 2.0.x. Either use an HBase release built against Hadoop 2.0.x or rebuild your HBase with hadoop.profile set to 2.0

-Dhadoop.profile=2.0
