Re: running unit test based on HBaseClusterTestCase

[Stack]

Do you have hadoop jars in your eclipse classpath?

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
