------------------------------------------------------------
Thanks [~eepayne] [~yufeigu] to watch this and works.
Except AbstractYarnScheduler is a @Private @Unstable class, the instance object
named nodeTracker's type is ClusterNodeTracker<N>, so I think it will work fine
with this patch.
{quote}protected final ClusterNodeTracker<N> nodeTracker =
new ClusterNodeTracker<>();

Thanks [~ajisakaa] [~cheersyang] works.
