HI moon The patch explained in https://issues.apache.org/jira/browse/ZEPPELIN-469 did not work.THat removing the line export CLASSPATH in bin/common.sh did not work. However, I have moved the jar file jackson-databind-2.5.3.jar from lib/ directory which actually worked. :-) Now, I have no exception
