------------------------------------
Summary: Impala's coordinator could not be connected after a
restart in custom cluster test in the ASAN build on ARM
Key: IMPALA-13167
URL: https://issues.apache.org/jira/browse/IMPALA-13167
Project: IMPALA
Issue Type: Bug
Reporter: Fang-Yu Rao
Assignee: Fang-Yu Rao
In an internal Jenkins run, we found that it's possible that Impala's
coordinator could not be connected after a restart that occurred after the
coordinator hit a DCHECK during the custom cluster test in the ASAN build on
ARM.
Specifically, in that Jenkins run, we found that Impala's coordinator hit the
DCHECK in [RuntimeProfile::EventSequence::Start(int64_t
start_time_ns)|https://github.com/apache/impala/blob/master/be/src/util/runtime-profile-counters.h#L656]
while running a query in
[ranger_column_masking_complex_types.test|https://github.com/apache/impala/blob/master/testdata/workloads/functional-query/queries/QueryTest/ranger_column_masking_complex_types.test#L724-L732]
that was run by
[test_column_masking()|https://github.com/apache/impala/blob/master/tests/authorization/test_ranger.py#L1916].
Since Impala daemons and the catalog server are restarted for each test in
test_ranger.py, the next test run after test_column_masking() should most
likely be passed. However it did not seem like this. We found that for the
following few tests (e.g., test_block_metadata_update()) in test_ranger.py,
Impala's pytest framework was not able to connect to the coordinator with the
following error and hence those tests failed.
