Usage

From source file:edu.umass.cs.gnsclient.client.integrationtests.ServerConnectTest.java

/**
 * arun: Coordinated operations generally need some settling time before
 * they can be tested at "any" replica. That is, read-your-writes
 * consistency is not ensured if a read following a write happens to go to a
 * different replica. Thus, we either need to wait for a long enough
 * duration and/or retransmit upon failure.
 *
 * I have inserted waitSettle() haphazardly at places. These tests need to
 * be systematically fixed by retrying if the expected answer is not found.
 * Simply using the async client to resend the request should suffice as
 * ReconfigurableAppClientAsync is designed to automatically pick "good"
 * active replicas, i.e., it will forget crashed ones for some time; clear
 * its cache, re-query, and pick randomly upon an active replica error; and
 * pick the replica closest by distance and load otherwise.
