-----------------------------
Code Review: https://gerrit.cloudera.org/c/12099/
> exportAuthenticationCredentials does not retry connectToCluster
> ---------------------------------------------------------------
>
> Key: KUDU-2387
> URL: https://issues.apache.org/jira/browse/KUDU-2387
> Project: Kudu
> Issue Type: Bug
> Components: java
> Affects Versions: 1.7.0
> Reporter: Todd Lipcon
> Assignee: Adar Dembo
> Priority: Critical
>
> TestSecurity has the following TODO:
> {code}
> // TODO(todd): it seems that exportAuthenticationCredentials() doesn't
> properly retry
> // in the case that there is no leader, even though
> NoLeaderFoundException is a RecoverableException.
> // So, we have to use a hack of calling listTabletServers, which _does_
> properly retry,
> // in order to wait for the masters to elect a leader.
> {code}
> It seems like this causes occasional failures of tests like KuduRDDTest -- I
> saw a case where the client failed to connect due to a negotiation timeout,
> and then didn't retry at all. It's not clear why the 3-second negotiation
> timeout was insufficient in this test case but likely just machine load or
> somesuch.
