["Chun-Hung Hsiao (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-8976?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16596700#comment-16596700 ] 

Chun-Hung Hsiao commented on MESOS-8976:
----------------------------------------

This is caused by MESOS-6231. The following [code|https://github.com/apache/mesos/blob/959fa0bbe6dcde60262bc131f851f5bb2d709d57/src/tests/utils.cpp#L59-L67] is stuck because the {{/metrics/snapshot}} is pending for more than 1hr:
{code:cpp}
  // TODO(neilc): This request might timeout if the current value of a
  // metric cannot be determined. In tests, a common cause for this is
  // MESOS-6231 when multiple scheduler drivers are in use.
  Future<http::Response> response = http::get(upid, "snapshot");

  AWAIT_EXPECT_RESPONSE_STATUS_EQ(http::OK().status, response);
  AWAIT_EXPECT_RESPONSE_HEADER_EQ(APPLICATION_JSON, "Content-Type", response);

  Try<JSON::Object> parse = JSON::parse<JSON::Object>(response->body);
{code}

> In an internal CI run, we observed a failure with this test where the scheduler seemed to be stuck repeatedly allocating resources to the agent for about 1 hour before getting timed out. See attached log for details.
