Example 13 with TestLayoutBuilder

use of org.corfudb.infrastructure.TestLayoutBuilder in project CorfuDB by CorfuDB.

the class ManagementViewTest method testSequencerFailover.

/**
     * Scenario with 3 nodes: SERVERS.PORT_0, SERVERS.PORT_1 and SERVERS.PORT_2.
     * We fail SERVERS.PORT_1 and then wait for one of the other two servers to
     * handle this failure, propose a new layout and we assert on the epoch change.
     * The failure is handled by ConserveFailureHandlerPolicy.
     * No nodes are removed from the layout, but are marked unresponsive.
     * A sequencer failover takes place where the next working sequencer is reset
     * and made the primary.
