joseluisll commented on PR #8638:
URL: https://github.com/apache/hadoop/pull/8638#issuecomment-5139523422
The cause of the error is a stale CI workspace: the 3 failed tests belong to
TestBlockTokenZeroLifetimeWithDFS, which I removed in the commit b0ce37d; the
compiled class survived in the Jenkins workspace and was picked up by surefire.
I reproduced this is my workspace: a mvn clean, compile and test works, but
if I paste into target/test-classes the TestBlockTokenZeroLifetimeWithDFS.class
from commit 150cd8d, then the exact same 3 errors of the CI appear.
Also, run #3 appears to have hung after 27 hours and produced no report.
could you trigger the build again? _On a clean workspace this should come
back green._
Thank you for your time.

> Reporter: jiang he
> Priority: Major

> When block access tokens are enabled and dfs.block.access.token.lifetime is
> set to 0, HDFS write operations fail with a DataStreamer error.
> Reproduced with Hadoop 3.4.3.
> The same test passes when dfs.block.access.token.lifetime is set to a normal
> positive value.
