Examples with AdminSlopStreamingVerifier voldemort.cluster.failuredetector.AdminSlopStreamingVerifier used on opensource projects

Example 1 with AdminSlopStreamingVerifier

use of voldemort.cluster.failuredetector.AdminSlopStreamingVerifier in project voldemort by voldemort.

the class StreamingSlopPusherTest method testPushForHostSwap.

/**
     * 
     * Procedure: 1. bring up 2-node cluster; 2. set up slop pusher job with the
     * cluster info; 3. replace node 1 by simply changing its port-ids, update
     * the cluster metadata to whole cluster; 4. run slop pusher job and it has
     * to fail; 5. setCluster in FD and the slop pusher job has to succeed
     * 
     * @throws InterruptedException
     * @throws IOException
