Examples with SyncGroupRequest org.apache.kafka.common.requests.SyncGroupRequest used on opensource projects

Example 1 with SyncGroupRequest

use of org.apache.kafka.common.requests.SyncGroupRequest in project kafka by apache.

the class WorkerCoordinatorTest method testJoinLeaderCannotAssign.

@Test
public void testJoinLeaderCannotAssign() {
    // If the selected leader can't get up to the maximum offset, it will fail to assign and we should immediately
    // need to retry the join.
    // When the first round fails, we'll take an updated config snapshot
    EasyMock.expect(configStorage.snapshot()).andReturn(configState1);
    EasyMock.expect(configStorage.snapshot()).andReturn(configState2);
    PowerMock.replayAll();
    final String memberId = "member";
    client.prepareResponse(groupCoordinatorResponse(node, Errors.NONE));
    coordinator.ensureCoordinatorReady();
    // config mismatch results in assignment error
    client.prepareResponse(joinGroupFollowerResponse(1, memberId, "leader", Errors.NONE));
    MockClient.RequestMatcher matcher = new MockClient.RequestMatcher() {

        @Override
        public boolean matches(AbstractRequest body) {
