------------------------------------------------------------
The test failures do not look related. TestBalancerWithMultipleNameNodes,
TestWebHdfsTimeouts, and TestEditLogTailer passed fine locally.
TestBPOfferService failed with or without your patch applied.
Just committed this to trunk. Thanks [~csun]!

> Currently the {{msync}} call is a dummy operation to observer without really
> syncing. Instead, it should:
> # Get the latest stateID from active NN.
> # Use the stateID to talk to observer NN and make sure it is synced.
