Example 1 with ZKJobMasterRegistrar

use of edu.iu.dsc.tws.common.zk.ZKJobMasterRegistrar in project twister2 by DSC-SPIDAL.

the class ZKJobMasterRegistrarExample method main.

/**
 * we assume that we have the Job Master IP address and the port number
 * We will register this pair of information on a ZooKeeper server
 * Workers will discover the Job Master address by querying this ZooKeeper server
 * <p>
 * If there is already a znode on the ZooKeeper with the same name,
 * we delete that znode. It must be from a previous registration session
 * <p>
 * Parameters:
 * the only parameter is the ZooKeeper server address
 * <p>
 * This class is used together with ZKJobMasterFinderExample.java
 * This class registers the Job Master and that class discovers it
