If you see an error similar to this during job submission, it indicates that the
HADOOP_CLASSPATH
is incorrectly configured:
ERROR security.UserGroupInformation: PriviledgedActionException as:<user> (auth:SIMPLE) cause:java.io.IOException: Cannot initialize Cluster. Please check your configuration formapreduce.framework.name and the correspond server addresses. java.io.IOException: Cannot initialize Cluster. Please check your configuration for mapreduce.framework.name and the correspond server addresses.
Solution: This issue is caused when
HADOOP_CLASSPATH
is incorrectly configured. To set
HADOOP_CLASSPATH
:
On the Tez Service host machine, edit
hadoop-env.sh
and modify the following parameter:export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$TEZ_HOME/*:$TEZ_HOME/lib/*
where,
$TEZ_HOME
is the location of the directory that contains all the Tez JAR files. By default,$TEZ_HOME
is set to/usr/lib/tez
.
