Work Description: ZanderXu opened a new pull request, #4674:
URL: https://github.com/apache/hadoop/pull/4674
### Description of PR
Improve Code with Lambda in org.apahce.hadoop.hdfs.server.namenode sub packages.
For example:
Current logic:
```
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);
}
});
}
```
Improved Code with Lambda:
```
public ListenableFuture<GetJournaledEditsResponseProto> getJournaledEdits(
long fromTxnId, int maxTransactions) {
return parallelExecutor.submit(() -> getProxy().getJournaledEdits(
journalId, nameServiceId, fromTxnId, maxTransactions));
}
```
