------------------------------------------------------------
I looked over the issue with [~rmetzger]. The actual reason seems to be that
the YARN containers get [killed at the end of the
test|https://github.com/apache/flink/blob/5e08e55caede0c81100d7032257133854de1155c/flink-yarn-tests/src/test/java/org/apache/flink/yarn/YARNSessionFIFOITCase.java#L192].
There's a race condition between stopping the TaskManager and stopping the
JobManager. If the JM is stopped first, there is a risk that the TM is trying
to access the JM's BLOB server at that moment. It loses the connection and
reports the connection problem. The exception ends up in the output of the
TaskManager and will trigger the test failure.
The following logs showcase this based on the build reported in the Jira
issues' description (application folder:
{{./container_1611618440792_0002_01_000001/}}).

The only strange thing is that the timetamp is not aligned. The TM receives the
{{SIGTERM}} at {{23:47:46,456}}, ~22s earlier than the JobManager and even
earlier than the test which is triggering the killing. It looks like there are
two test running on the same application nodes. There are also four subfolders
{{container_1611618440792_000*_01_000002/}} containg 2 {{taskmanager.log}} and
2 {{jobmanager.log}}. Could it be that two Yarn tests are running in parallel
and one killing triggered the killing of the other one? The second
{{taskmanager.log}} also received a {{SIGTERM}} but at {{23:48:08,029}} which
would match our timestamps of the {{jobmanager.log}} referred to above.
was (Author: mapohl):
I looked over the issue with [~rmetzger]. The actual reason seems to be that
the YARN containers get [killed at the end of the
test|https://github.com/apache/flink/blob/5e08e55caede0c81100d7032257133854de1155c/flink-yarn-tests/src/test/java/org/apache/flink/yarn/YARNSessionFIFOITCase.java#L192].
There's a race condition between stopping the TaskManager and stopping the
JobManager. If the JM is stopped first, there is a risk that the TM is trying
to access the JM's BLOB server at that moment. It loses the connection and
reports the connection problem. The exception ends up in the output of the
TaskManager and will trigger the test failure.
The following logs showcase this based on the build reported in the Jira
issues' description (application folder:
{{./container_1611618440792_0002_01_000001/}}).

The JobManager's logs (see above) show that the job finished successfully
({{2021-01-25 23:48:07,80}}). That (or probably even the two log messages

The JobManager received the {{SIGTERM}} at {{23:48:08,008}}. The process got
killed.
In the meantime, the TaskManager (see below) tries to access the BLOB server

The only strange thing is that the timetamp is not aligned. The TM receives the
{{SIGTERM}} at {{23:47:46,456}}, ~22s earlier than the JobManager and even
earlier than the test which is triggering the killing. It looks like there are
two test running on the same application nodes. There are also four subfolders
{container_1611618440792_000*_01_000002/}} containg 2 {{taskmanager.log}} and 2
{{jobmanager.log}}. Could it be that two Yarn tests are running in parallel and
one killing triggered the killing of the other one? The second
{{taskmanager.log}} also received a {{SIGTERM}} but at {{23:48:08,029}} which
would match our timestamps of the {{jobmanager.log}} referred to above.
