    Description

      TestBalancerRPCDelay.testBalancerRPCDelayQpsDefault fails intermittently when the number of blocks does not match the expected. In testBalancerRPCDelay, it seems like some datanodes will not be up by the time we fetch the block locations.

      I see the following stack trace:
