             Summary: Enhance easy-to-use feature and support concurrent jobs
                 Key: SINGA-30
                 URL: https://issues.apache.org/jira/browse/SINGA-30
             Project: Singa
          Issue Type: New Feature
            Reporter: Sheng Wang


To let users run singa jobs easily and concurrently, we need to enhance the 
functionalities zookeeper services and bash scripts. There are several 
milestones:

1. Automatically launch a number of processes in the cluster
  User only need to provide a global host list that singa can use, instead of 
providing a host list for each job.

2.  Support running multiple singa jobs at the same time
  We need to ensure that all runtime information is stored in separated 
zookeeper paths. The first step is to implement a tool that generates a unique 
job id for each job, and let zookeeper put contents into different paths.

3. Provide an easy-to-use script for users to run and kill singa jobs, such as:
$./singa.sh start -conf=CONF_DIR
$./singa.sh kill -job=JOB_ID

We will get these done step by step.
