Yes, I included all the necessary jar files I think. I guess my problem is probably related to my eclipse setup.
I can create a MiniDFSCluster object by running my application in command line (e.g., bin/hadoop myApplicationClass) , and a MiniDFSCluster object is created inside the main function of myApplicationClass. But I can NOT run this program within eclipse, probably I did not do it in the right way. I got the similar error message saying java.lang.NoSuchMethodError: org.apache.hadoop.security. > > > UserGroupInformation.setCurrentUser(Lorg/apache/hadoop/security/UserGroupInformation;)V > at org.apache.hadoop.hdfs.MiniDFSCluster.<init>(MiniDFSCluster.java:236) > at org.apache.hadoop.hdfs.MiniDFSCluster.<init>(MiniDFSCluster.java:119) > Could you guys please give me more hint?
