> I've observed that chooseTargets in ReplicationWork may pass incomplete 
> srcPath (not starting with '/') to block placement policy.
> It is possible that srcPath is extensively used in custom placement policy. 
> In this case, the incomplete srcPath may further cause AssertionError if try 
> to get INode with it inside placement policy.
