> Key: KUDU-2771
> URL: https://issues.apache.org/jira/browse/KUDU-2771
> Project: Kudu
> Issue Type: Improvement
> Components: util
> Affects Versions: 1.10.0
> Reporter: Alexey Serbin
> Priority: Major
> Labels: newbie
>
> Currently, in {{KuduClient::Data::ConnectToClusterAsync}} and in
> {{SentryPrivilegesFetcher::GetSentryPrivileges}} there is a pattern when
> concurrent requests with the same parameters are queued and multiple threads
> are waiting for something to be executed just once. When the result is ready
> to be picked up (or a failure happened), the threads are awoken and fed with
> appropriate information.
> It would be nice to factor out, unify, and generalize that code into a
> library function (or a class with appropriate methods) somewhere under
> {{src/kudu/util}}.
