> PhoenixHBaseLoader should implement both OrderedLoadFunc and CollectableLoadFunc just like HBaseStorage. There is nothing special that needs to be done other than implementing a single method. As in HBaseStorage, it is up to the user to ensure that the required constraints are not violated.
> {code:java}
> public void ensureAllKeyInstancesInSameSplit() throws IOException {
> /**
> * no-op because hbase keys are unique
> * This will also work with things like DelimitedKeyPrefixRegionSplitPolicy
> * if you need a partial key match to be included in the split
> */
> LOG.debug("ensureAllKeyInstancesInSameSplit");
