HDFS-16695. Improve code with Lambda in org.apache.hadoop.hdfs.servernamenode package
Description of PR
Improve Code with Lambda in org.apahce.hadoop.hdfs.server.namenode package.
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));
}
This is a massive PR. I'm not sure if it is worth though. I would prefer to scope it too.

Personally, I think this optimization should still be valuable, I hope that the submitted pr is not at the class level, at least at the moudle level.

I wouldn't go for one per class but maybe subpackage. I also think this PR is doing a couple of things more other than adding lambdas. For example, adjusting for iterations.

I wouldn't go for one per class but maybe subpackage. I also think this PR is doing a couple of things more other than adding lambdas. For example, adjusting for iterations.
I understand your suggestion that the lambda should be tuned with other code modifications, not just the lambda code.
Thanks @goiri @slfan1989 for your review.
- First, I will remove some code that has nothing to do with lambdas
- Second, I will split this PR at the subPackage Level, such as:
org.apache.hadoop.hdfs.server.namenode,org.apache.hadoop.hdfs.server.namenode.ha
@goiri @slfan1989 Sir, I have updated this patch, please help me review it. Thanks
- Just improved code with Lambda in namenode package
- Removed some code that has nothing to do with lambdas
