[jira] [Resolved] (BIGTOP-3426) Flink smoke test fails with
fedora-31 and debian-10 on arm64
[ https://issues.apache.org/jira/browse/BIGTOP-3426?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kengo Seki resolved BIGTOP-3426.
--------------------------------
Resolution: Not A Bug
After some Jenkins tweaking, increasing memory limit (4g to 8g) and decreasing the number of nodes (3 to 1) seem to stablize this test.
(The reason of the latter is that our server resource is limited, and requesting package files from three nodes at the same time often results in a network failure)
So it's not a problem about smoke test itself, but an environmental one. Closing this, sorry for bothering you [~yqGu]!
