Matthew Sharp commented on YARN-10250:
--------------------------------------
The launch-container script will fail on any non-zero return code, since that
is debugging information only, one quick approach is to force those commands to
always return true so the container relaunch is not impacted.
> Container Relaunch - find: File system loop detected
> ----------------------------------------------------
>
> Key: YARN-10250
> URL: https://issues.apache.org/jira/browse/YARN-10250
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 3.2.0
> Reporter: Matthew Sharp
> Priority: Major
>
> Hive LLAP YARN service tries to relaunch from a container failure and when it
> retries on the same node we are seeing it fail with:
> {code:java}
> find: File system loop detected; ‘./lib/llap-27Apr2020.tar.gz’ is part of the
> same file system loop as ‘./lib’. {code}
>
> YARN-8667 attempted to clean up the prior symlinks before relaunching, but in
> this case it still exists since it recreates the symlinks right before trying
> to output to directory.info for logging.
>
> The following line appears to be the culprit:
> [https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/java/org/apache/hadoop/yarn/server/nodemanager/containermanager/launcher/ContainerLaunch.java#L1346]
