Dear all, I'm trying to run the examples of Hadoop on Kepler 2.4, but get some problems with it. When I start the Hadoop service (with correct passwords as required) with:
*bin/start-hadoop.sh* *The output is as the following and the worklows cannot be run:* bin bin=. bin=/home/cloudera/KeplerData/workflows/module/hadoop-1.0.0/tools/bin starting namenode, logging to /home/cloudera/KeplerData/workflows/module/hadoop-1.0.0/tools/bin/../logs/hadoop-cloudera-namenode-quickstart.cloudera.out cloudera@localhost's password: localhost: starting datanode, logging to /home/cloudera/KeplerData/workflows/module/hadoop-1.0.0/tools/bin/../logs/hadoop-cloudera-datanode-quickstart.cloudera.out cloudera@localhost's password: localhost: starting secondarynamenode, logging to /home/cloudera/KeplerData/workflows/module/hadoop-1.0.0/tools/bin/../logs/hadoop-cloudera-secondarynamenode-quickstart.cloudera.out localhost: Exception in thread "main" java.lang.NoClassDefFoundError: com.sun.security.auth.UnixPrincipal localhost: at org.apache.hadoop.security.UserGroupInformation.<clinit>(UserGroupInformation.java:313) localhost: at java.lang.Class.initializeClass(libgcj.so.10) localhost: at org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode.initialize(SecondaryNameNode.java:144) localhost: at org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode.<init>(SecondaryNameNode.java:125) localhost: at org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode.main(SecondaryNameNode.java:579) DEPRECATED: Use of this script to execute hdfs command is deprecated.
