Jean,Thank you.
Now i can start my hbase 0.20 shell and it does work in shell.
But I am still puzzled how to run my own java program to use hbase 0.20 api.
In the 0.19.3 version, i can run the java program with add hbase-* .jar and
hadoop-*.jar to my classpath.
Now i change the jar to 0.20, it cann't work.
The error messges is :
