             Summary: CreateSession should be reject when there is too more child process "spark-submit" is running
                 Key: LIVY-412
                 URL: https://issues.apache.org/jira/browse/LIVY-412
             Project: Livy
          Issue Type: Improvement
          Components: Server
    Affects Versions: 0.4
            Reporter: Hong Shen


In our cluster, livy server run with spark yarn cluster mode, when createSession request is too frequently, livyServer will start too more spark-submit child process, it will cause the machine oom. I think livy server should reject the create session request when there is too more spark-submit child process. I have fix it in our own cluster.
