Hi, folks, I have encountered a strange error when I am trying to upgrade from cdh4 to cdh5.1.3.
I have a unit test based on miniMRcluster and ClusterMapReduceTestCase. It runs successfully with cdh 4. After I have changed my maven setting to upgrade to cdh5. The running always failed. I have tried to isolate the problem. So I used the standard unit test (https://svn.apache.org/repos/asf/hadoop/common/trunk/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-jobclient/src/test/java/org/apache/hadoop/mapred/TestMiniMRClientCluster.java) and compile it with my maven setting, then I reproduced the same error by only testing testRestart(). 22596 [main] INFO org.apache.hadoop.mapreduce.v2.hs.JobHistory - Stopping JobHistory 22596 [main] INFO org.apache.hadoop.mapreduce.v2.hs.JobHistory - Stopping History Cleaner/Move To Done 22597 [Thread[Thread-184,5,main]] ERROR org.apache.hadoop.security.token.delegation.AbstractDelegationTokenSecretManager - ExpiredTokenRemover received java.lang.InterruptedException: sleep interrupted 22597 [main] INFO org.apache.hadoop.hdfs.MiniDFSCluster - Shutting down the Mini HDFS Cluster 22597 [main] INFO org.apache.hadoop.hdfs.MiniDFSCluster - Shutting down DataNode 1 22598 [main] WARN org.apache.hadoop.hdfs.server.datanode.DirectoryScanner - DirectoryScanner: shutdown has been called The test should be compatible for both MR1 and MR2. I also tried to overwrite some Yarn configuration, but it didn't help. I tried to google the related issue, but no luck for this particular issue.Any comments or Help are appreciated. Thanks so much! My mvn configuration part is as follows, <version.hadoop>2.3.0-cdh5.1.3</version.hadoop> <version.hadoop.core>2.3.0-cdh5.1.3</version.hadoop.core> <version.hadoop.minicluster>2.3.0-cdh5.1.3</version.hadoop.minicluster> <dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-client</artifactId> <version>${version.hadoop}</version> </dependency> <dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-minicluster</artifactId> <version>${version.hadoop.minicluster}</version> <exclusions> <exclusion> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>${project.groupId}</groupId> <artifactId>common-hadoop</artifactId> <version>${project.version}</version> </dependency> Best regards, Lumin Zhang
