> The test {{TestRMWebServicesDelegationTokenAuthentication.testCancelledDelegationToken}} sometimes fails with the following error:
> {noformat}
> java.io.IOException: Server returned HTTP response code: 400 for URL: http://localhost:8088/ws/v1/cluster/delegation-token
> at org.apache.hadoop.yarn.server.resourcemanager.webapp.TestRMWebServicesDelegationTokenAuthentication.cancelDelegationToken(TestRMWebServicesDelegationTokenAuthentication.java:462)
> at org.apache.hadoop.yarn.server.resourcemanager.webapp.TestRMWebServicesDelegationTokenAuthentication.testCancelledDelegationToken(TestRMWebServicesDelegationTokenAuthentication.java:283)
> {noformat}
> The problem is that for whatever reason, Jetty seems to execute the token cancellation REST call twice. First we get HTTP 200 OK, but the second request fails with HTTP 400 Bad Request.
> The {{MockRM}} instance is static. Something could be a problem in this class and it turned out that using separate {{MockRM}} instances solves the flakiness.
