> Key: IMPALA-8389
> URL: https://issues.apache.org/jira/browse/IMPALA-8389
> Project: IMPALA
> Issue Type: Bug
> Components: Infrastructure
> Affects Versions: Impala 3.2.0
> Reporter: radford nguyen
> Assignee: radford nguyen
> Priority: Minor
> Original Estimate: 1h
> Remaining Estimate: 1h

> h3. Brief
> CustomClusterTestSuite always waits for 3 daemons on startup instead of {{cluster_size}} daemons when {{impala_log_dir}} is specified.
> h3. Description
> The {{@CustomClusterTestSuite.withArgs}} decorator allows a user to specify a custom cluster size for the test case being decorated. However, when this option is specified in conjunction with {{impala_log_dir}}, it will fail to wait for the correct number of daemons if any value other than {{DEFAULT_CLUSTER_SIZE}} is used.
> The root cause is the difference in how the cluster is started with and without {{impala_log_dir}}: [https://github.com/apache/impala/blob/3.2.0/tests/common/custom_cluster_test_suite.py#L147]
> h3. To Reproduce:
> * add {{cluster_size=5}} to decorator of test_grant_revoke in tests/authorization/test_ranger.py
> * $ impala-py.test tests/authorization/test_ranger.py
> * observe pass
> * add {{impala_log_dir=whatev}} to decorator of test_grant_revoke
> * $ impala-py.test tests/authorization/test_ranger.py
> * observe fail during cluster startup:
> ** 2019-04-04 14:25:54,140 INFO MainThread: Waiting for num_known_live_backends=3. Current value: 5
