------------------------------------
Summary: Jenkins truncates logs excessively for failing tests.
Key: BEAM-10262
URL: https://issues.apache.org/jira/browse/BEAM-10262
Project: Beam
Issue Type: Bug
Components: build-system, testing
Reporter: Brian Hulette

https://issues.apache.org/jira/browse/BEAM-9976?focusedCommentId=17134617&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17134617
The [code for the jenkins junit
plugin|https://github.com/jenkinsci/junit-plugin/blob/master/src/main/java/hudson/tasks/junit/CaseResult.java#L190]
indicates stdout/stderr logs should be truncated to 1MiB for failing runs, and
just 1 KiB for passing runs. However _all_ Beam tests seem to be truncated to 1
KiB, not just passing runs. This can make it very difficult to debug flaky
tests, since they are challenging to reproduce locally, and nearly all the
relevant information from the failures is removed.
