Description

As per the unit test log in https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/35754/

15/06/24 23:09:10.210 Thread-3495 INFO ReceiverTracker: Starting 1 receivers

15/06/24 23:09:14.270 ForkJoinPool-4-worker-29 INFO StreamingListenerSuiteReceiver: Reporting error and sleeping

it needs at least 4 seconds to receive all receiver events in this slow machine, but `timeout` for `eventually` is only 2 seconds.

We can increase `timeout` to make this test stable.
