Amar Kamat updated MAPREDUCE-677:
---------------------------------
Release Note: TestNodeRefresh sometimes timed out. This happened because
the test started a MR cluster with 2 trackers and ran a half-waiting-mapper
job. Tasks that have id > total-maps/2 wait for a signal. Because of 2
trackers, the tasks got scheduled out of order (locality) and hence the job got
stuck. The fix is to start only one tracker and then add a new tracker later.
