Summary: Improve Code With Lambda in hadoop-hdfs module
Key: HDFS-16695
URL: https://issues.apache.org/jira/browse/HDFS-16695
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: ZanderXu
Assignee: ZanderXu
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}
