start master failed with error

[Garry Chen]

Hi All,
Error when issued start-master.sh as following.  Even I have my 
CLASSPATH=/u01/app/jdk1.8.0_60/lib:/u01/app/apache-hive-1.2.1-bin/lib:/u01/app/slf4j-1.7.12
 set in environment profile.  Can anyone help?  Thank you very much.

slf4j classes would already be present in your spark-assembly jar (do a *jar
tf 
/u01/app/spark-1.4.1-bin-without-hadoop/lib/spark-assembly-1.4.1-hadoop2.2.0.jar
| grep "org/slf4j/Logger"*)
