Example 1 with HealthCheckFailedException

use of org.apache.hadoop.ha.HealthCheckFailedException in project hadoop by apache.

@Test
public void testCheckHealth() throws Exception {
    assertEquals(0, runTool("-checkHealth", "nn1"));
    Mockito.verify(mockProtocol).monitorHealth();
    Mockito.doThrow(new HealthCheckFailedException("fake health check failure")).when(mockProtocol).monitorHealth();
    assertEquals(-1, runTool("-checkHealth", "nn1"));
    assertOutputContains("Health check failed: fake health check failure");
}

Example 2 with HealthCheckFailedException

use of org.apache.hadoop.ha.HealthCheckFailedException in project hadoop by apache.
