Cannot initialize Cluster. Please check your configuration for mapreduce.framework.name and the correspond server addresses-submiting job2remoteClustr

Question

I recently upgraded my cluster from Apache Hadoop1.0 to CDH4.4.0. I have a weblogic server in another machine from where i submit jobs to this remote cluster via mapreduce client. I still want to use MR1 and not Yarn. I have compiled my client code against the client jars in the CDH installtion (/usr/lib/hadoop/client/*)

Am getting the below error when creating a JobClient instance. There are many posts related to the same issue but all the solutions refer to the scenario of submitting the job to a local cluster and not to remote and specifically in my case from a wls container.

JobClient jc = new JobClient(conf);

Cannot initialize Cluster. Please check your configuration for mapreduce.framework.name and the correspond server addresses.

But running from the command prompt on the cluster works perfectly fine.

Appreciate your timely help!

I had a similar error and added the following jars to classpath and it worked for me: hadoop-mapreduce-client-jobclient-2.2.0.2.0.6.0-76:hadoop-mapreduce-client-shuffle-2.3.0.jar:hadoop-mapreduce-client-common-2.3.0.jar
