question: public void write ( String key , byte [ ] newValue ) throws Exception { Map < String , byte [ ] > entry = new HashMap < > ( ) ; entry . put ( key , newValue ) ; write ( entry ) ; }
target:  Performs the best effort of updating ZK node {basePath}/{key} to the provided value. The semantics provided are as follows: The value is written regardless of the current value associated with the key. If the key doesn't exist and we lose the race to create the key, we will throw an exception.
