             Summary: Configuring Apache Flink Local Set up with Pseudo distributed Yarn
                 Key: FLINK-8615
                 URL: https://issues.apache.org/jira/browse/FLINK-8615
             Project: Flink
          Issue Type: Bug
    Affects Versions: 1.4.0
         Environment: Mac Os, Hadoop 2.8.3 and Flink 1.4.0
            Reporter: Karrtik Iyer


I have set up HADOOP 2.8.3 and YARN on my Mac machine in Pseudo distributed mode, following this blog: [Hadoop In Pseudo Distributed Mode|http://zhongyaonan.com/hadoop-tutorial/setting-up-hadoop-2-6-on-mac-osx-yosemite.html] I have been able to successfully start hdfs and yarn. And also able to submit Map reduce jobs.

After that I have download Apache Flink 1.4 from [here|http://redrockdigimark.com/apachemirror/flink/flink-1.4.0/flink-1.4.0-bin-hadoop28-scala_2.11.tgz]. Now I am trying to set up Flink on the above Yarn cluster by following the steps [here|https://ci.apache.org/projects/flink/flink-docs-release-1.4/ops/deployment/yarn_setup.html]. When I try to run /bin/yarn-session.sh -n 4 -jm 1024 -tm 4096, I am getting below error which I am unable to resolve. Can someone please advise and help me with the same?
