> Improve Code with Lambda in org.apahce.hadoop.hdfs.server.namenode sub packages.
> For example:
> Current logic:
> {code:java}
> public ListenableFuture<GetJournaledEditsResponseProto> getJournaledEdits(
> long fromTxnId, int maxTransactions) {
> return parallelExecutor.submit(
> new Callable<GetJournaledEditsResponseProto>() {
> @Override
> public GetJournaledEditsResponseProto call() throws IOException {
> return getProxy().getJournaledEdits(journalId, nameServiceId,
> fromTxnId, maxTransactions);
> }
> });
> } {code}
> Improved Code with Lambda:
> {code:java}
> public ListenableFuture<GetJournaledEditsResponseProto> getJournaledEdits(
> long fromTxnId, int maxTransactions) {
> return parallelExecutor.submit(() -> getProxy().getJournaledEdits(
> journalId, nameServiceId, fromTxnId, maxTransactions));
> } {code}
