I was wondering if there was a function in hbase that would translate to
running this code "atomically" on the "server side"...
checkAndPut(byte[] key, byte[] previousValue, byte[] newValue)
OR maybe there is something "similar" to the code below in hbase????
such that this code is run(so I would 1. Get the latest value in db and
2. my put would fail in cases where another server put it first)....
* if (previousValue == null && !map.containsKey(key))
* return map.put(key, value);
* else if(previousValue != null &&
previousValue.equals(map.get(key)))
* return map.put(key, value);
* else
* return map.get(key);
