ASF GitHub Bot updated HADOOP-19964:
------------------------------------
Labels: pull-request-available (was: )
> Restore TimedOutTestsListener thread dumps on test timeout
> ----------------------------------------------------------
>
> Key: HADOOP-19964
> URL: https://issues.apache.org/jira/browse/HADOOP-19964
> Project: Hadoop Common
> Issue Type: Test
> Reporter: Jose Luis López
> Priority: Critical
> Labels: pull-request-available
>
> Goal: a test that fails on @Timeout prints a full thread dump into its
> surefire report. Today it prints nothing, and a timeout without thread state
> is undiagnosable after the fact.
>
> This is a regression. TimedOutTestsListener (HADOOP-8755, 2012) did exactly
> this until the JUnit 5 migration (HADOOP-19415 Part4) left it implementing no
> listener interface. The Surefire "listener" property that 8 poms still carry
> registers nothing.
>
> Fix:
> * Reimplement it as a JUnit Platform TestExecutionListener, auto-registered
> via META-INF/services in the hadoop-common test artifact.
> * Remove the dead "listener" property from the 8 poms.
> * -Dhadoop.test.timedout.dump=false turns it off;
> -Dhadoop.test.timedout.dump.limit (default 5) caps dumps per JVM.
>
> Covers timeouts that fail through JUnit. Does not cover Surefire's fork kill
> (forkedProcessTimeoutInSeconds), which halts the JVM and bypasses listeners.
> Complements HADOOP-19950, whose CI upload globs already capture the report
> files these dumps land in.
>
> The listener activates for every consumer of the hadoop-common test artifact,
> including HBase, Ozone, Hive and Tez: needs a release note.
>
> Test-scope only; no production code is touched.
