}
I've added all the log4j2 jar files in classpath variable in ~/.bashrc file.
but still getting same error and I've already wasted an entire day in resolving
this, but no solution yet.
And apache avro jar(avro-1.4.1.jar) is also in classpath.
Still the problem persists.
I've these jar files in my classpath : log4j12-api-2.0-beta3.jar,
log4j-core-2.0-beta3.jar, log4j-flume-ng-2.0-beta3.jar,
log4j-jcl-2.0-beta3.jar, log4j-slf4j-impl-2.0-beta3.jar, avro-1.4.1.jar.

Pradeep Kanchgar
