Description

AutoCreatedQueueTemplate calculates wrong wildcard level so a root.* wildcard won't match for a root.queue for example.

Here the min should be min(queuePathMaxIndex, MAX_WILDCARD_LEVEL), instead of this:

int supportedWildcardLevel = Math.min(queuePathMaxIndex - 1,
        MAX_WILDCARD_LEVEL);

Test code to validate the fix:

  @Test
  public void testWildcardAfterRoot() {
    conf.set(getTemplateKey("root.*", "acl_submit_applications"), "user");
    AutoCreatedQueueTemplate template =
        new AutoCreatedQueueTemplate(conf, new QueuePath("root.a"));
    template.setTemplateEntriesForChild(conf, "root.a");

    Assert.assertEquals("acl_submit_applications is set", "user",
        template.getTemplateProperties().get("acl_submit_applications"));
  }
