Change subject: IMPALA-9755: Flaky test: test_global_exchange_counters ...................................................................... IMPALA-9755: Flaky test: test_global_exchange_counters De-flake TestObservability.test_global_exchange_counters in test_observability.py. IMPALA-6984 added a feature to send a Cancel RPC to running fragments when the coordinator fragment fetches all rows defined by a limit. This causes fragments to terminate early (which is a good thing). However, test_global_exchange_counters expects each fragment to produce some rows, which is why it recently became flaky. This patch modifies test_global_exchange_counters so that it allows for some fragments to produce 0 rows. Testing: * Ran test_observability.py locally * Looped 8 concurrent streams of test_global_exchange_counters for an hour, no failures (previously I was able to reproduce the test issue within 5 minutes) Change-Id: Icb3a1b5ccb5695eb71343e96cc830f12d5c72f1e --- M tests/query_test/test_observability.py 1 file changed, 7 insertions(+), 4 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/60/15960/1 -- To view, visit http://gerrit.cloudera.org:8080/15960 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: Icb3a1b5ccb5695eb71343e96cc830f12d5c72f1e Gerrit-Change-Number: 15960 Gerrit-PatchSet: 1 Gerrit-Owner: Sahil Takiar <[email protected]>
