> Do Not Use Both Map containsKey and get Methods in Replication Sink

> Key: HBASE-20209
> URL: https://issues.apache.org/jira/browse/HBASE-20209
> Project: HBase
> Issue Type: Improvement
> Components: Replication
> Affects Versions: 2.0.0
> Reporter: BELUGA BEHR
> Assignee: BELUGA BEHR
> Priority: Trivial

> {code:title=ReplicationSink.java}
> String tableName = table.getNameWithNamespaceInclAsString();
> if (bulkLoadHFileMap.containsKey(tableName)) {
> List<Pair<byte[], List<String>>> familyHFilePathsList =
> bulkLoadHFileMap.get(tableName);
> boolean foundFamily = false;
> for (int i = 0; i < familyHFilePathsList.size(); i++) {
> Pair<byte[], List<String>> familyHFilePathsPair =
> familyHFilePathsList.get(i);
> if (Bytes.equals(familyHFilePathsPair.getFirst(), family)) {
> // Found family already present, just add the path to the
> existing list
> familyHFilePathsPair.getSecond().add(pathToHfileFromNS);
> foundFamily = true;
> break;
> }
> }
> {code}
> I propose that this code does not use the Map methods _containsKey_ *and*
> _get_. Simply use the _get_ method once and check a _null_ return value to
> check for existence. Saves a trip to the Map data structure for each call.
> Also, use enhanced for loop.
