> Key: HDFS-16695
> URL: https://issues.apache.org/jira/browse/HDFS-16695
> Project: Hadoop HDFS

> Improve Code with Lambda in hadoop-hdfs module.
> 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}
