---------------------------------
Summary: 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
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.
