Example 1 with SnapshotManagementRequest

use of org.apache.ratis.protocol.SnapshotManagementRequest in project incubator-ratis by apache.

the class SnapshotManagementTest method runTestTakeSnapshotWithConfigurableGap.

void runTestTakeSnapshotWithConfigurableGap(CLUSTER cluster) throws Exception {
    RaftClientReply snapshotReply;
    final RaftServer.Division leader = RaftTestUtil.waitForLeader(cluster);
