----------------------------
Summary: Increase the timeout interval for
TestSentryClientMetrics.Basic
Key: KUDU-2882
URL: https://issues.apache.org/jira/browse/KUDU-2882
Project: Kudu
Issue Type: Improvement
Components: master
Affects Versions: 1.10.0
Reporter: HeLifu
When I run the test cases of 1.10.0-RC2, the 'TestSentryClientMetrics.Basic' is
a little bit strange. Sometimes it works, but sometime it doesn't.
Today, I took a close look at the output log and found some useful info:

{code}
Then I looked through the file 'sentry_authz_provider-test.cc', it seems the
timeout value is too short:
[https://github.com/apache/kudu/blob/5c652defff422f908dacc11011dc6ae59bf49be5/src/kudu/master/sentry_authz_provider-test.cc#L1396]
Perhaps, we can increase this value (default 60 seconds) to 4 or 5 seconds to
avoid the failures, though Alexey Serbin(not sure) and I have this problem.
