So, essentially,
when you use the put method, putIfAbsent method or clear operation, you would need your node to be added/updated to acquire a lock. e.g. : in Java, its done by synchronize(Node) block.

Constructor(int capacity) {
		//no threading required
	}
	public Object put() {
		//Calculate hash function
		//Traverse through the keys based on hash function
		//synchronize (Node) {
			//regular put procedure
		}
	}
        get (Key) {
		//Probably check if the lock is acquired
		//If yes, then wait for lock to be released
		//get as in a regular hashMap()
    	}
}
