Subject Caused by: java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext
Date Mon, 20 Jun 2016 08:54:17 GMT
Hello users,

I am getting a error while running my flink jar from command line or web
frontend, the error does not arises when I run the program from Intellij
IDE. I am posting the error below.






























*org.apache.flink.client.program.ProgramInvocationException: The main
method caused an error.    at

at org.apache.flink.client.CliFrontend.main(CliFrontend.java:1243)Caused
by: java.lang.IllegalArgumentException: LoggerFactory is not a Logback
LoggerContext but Logback is on the classpath. Either remove Logback or the
competing implementation (class org.slf4j.impl.Log4jLoggerFactory loaded
from
file:/home/royd1990/Downloads/flink-1.0.3/lib/slf4j-log4j12-1.7.7.jar). If
you are using WebLogic you will need to add 'org.slf4j' to
prefer-application-packages in WEB-INF/weblogic.xml Object of class
[org.slf4j.impl.Log4jLoggerFactory] must be an instance of class

>From what I understand it is having a issue with conflict of two logger
classes. However in the pom.xml I have excluded the logger from flink
dependency to be excluded. Also attaching part of  my pom.xml for better
understanding.
