Example 5 with FAILED

use of com.hazelcast.jet.core.JobStatus.FAILED in project hazelcast by hazelcast.

the class WatermarkCoalescer_TerminalSnapshotTest method test.

@Test
public void test() throws Exception {
    /*
        This test tests the issue that after a terminal barrier is processed, no other work should
        be done by the ProcessorTasklet or CIES after that (except for emitting the DONE_ITEM).
        Also, if at-least-once guarantee is used, the tasklet should not continue to drain
        the queue that had the barrier while waiting for other barriers.

        Specifically, the issue was that in at-least-once mode the DONE_ITEM was processed
        after the terminal barrier while waiting for the barrier on other queues/edges. The
        DONE_ITEM could have caused a WM being emitted after the barrier, which is ok
        for the at-least-once mode, but the terminal snapshot should behave as if exactly-once
        mode was used.

        This test ensures that we're waiting for a WM in coalescer (by having a stream skew)
        and then does a graceful restart in at-least-once mode and checks that the results are
        correct.
