Hello All,
In my own application, I have a unit test case which extends
HBaseClusterTestCase in order to test some of my operation over HBase
cluster. I override the setup function in my own test case, and this setup
function begins with super.setup() function call.
When I try to run my unit test from within Eclipse, I got the following
error:
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)
at
org.apache.hadoop.hbase.HBaseClusterTestCase.setUp(HBaseClusterTestCase.java:123)
I included the hadoop-0.20.1-core.jar in my classpath, since this jar file
contains the org.apache.hadoop.security.UserGroupInformation class.
Could anybody give me some hint on how to solve this problem?
Thank you very much,
Guohua
