-----------------------------------
Summary: HDFS kerberos timeout tests take 7+ minutes to finish
Key: SENTRY-2069
URL: https://issues.apache.org/jira/browse/SENTRY-2069
Project: Sentry
Issue Type: Test
Components: Sentry
Reporter: Sergio Peña
While taking a look at the time spent on the sentry tests, I found that the
HDFS timeout tests take 7+ minutes to finish:
{noformat}
[INFO] Running org.apache.sentry.hdfs.TestKrbConnectionTimeout
[INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 449.31 s
- in org.apache.sentry.hdfs.TestKrbConnectionTimeout
{noformat}
I see that the test sleeps for 400s before attempting to reconnect to HDFS.
{noformat}
@Test
public void testConnectionAfterTicketTimeout() throws Exception {
Thread.sleep(400000);
connectToHdfsSyncService();
}
{noformat}
1. I think we could reduce the ticket renewal time to speed the test case (See
MiniKdc.MAX_RENEWABLE_LIFETIME).
2. The test case is not verifying the renewal was done. How can we verify this
renewal is correct? There is some code on the SentryTransportFactory.open() to
renew the ticket, but that is never triggered when I was doing tests.
We should improve this test case to speed the test and check that the renewal
is working.
