----------------------------------------------
Summary: Kudu tests fail when with use_hybrid_clock=false
Key: IMPALA-7790
URL: https://issues.apache.org/jira/browse/IMPALA-7790
Project: IMPALA
Issue Type: Bug
Reporter: Thomas Tauber-Marshall
Assignee: Thomas Tauber-Marshall
Since IMPALA-6812, we've run many of our tests against Kudu at the
READ_AT_SNAPSHOT scan level, which ensures consistent results. This scan level
is only supported if Kudu is run with the flag --use_hybrid_clock=true (which
is the default).
This hasn't generally been a problem in the past, as we've primarily run
Impala's functional tests against the minicluster, where Kudu is configured
correctly, but there's been some effort around running these tests against real
clusters, in which case --use_hybrid_clock=false may be set.
We should at a minimum recognize this situation and skip the tests.
