> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager, test

> 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.
