Note: The image below shows the process being done using 7-zip, but you can use another software

The JCL has a simple deploy that enables the Server to discover and auto start when it's not found a Server in the network, thus you don't need to specify it's adress at the configuration file. All you need to do is start the Server.bat and the Server installation will be performed. 


After starting the Server, a command prompt window will open. If everything goes well, the "JCL server ok" message will be printed


JCL bat and sh files to start Server, Super-peers and Hosts configure Java heap. By default JCL configures 2GB, as the figure below illustrates. JCL BIG Sorting requires at least 8GB per JCL host, since it processes Terabytes of data. Raspberry Pi clusters normally requires 128 or 256 megabytes for Java heap. Just DO NOT FORGET TO CONFIGURE THE JAVA HEAP ACCORDING TO YOUR NEEDS!!
