>                 Key: YARN-9776
>                 URL: https://issues.apache.org/jira/browse/YARN-9776
>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: log-aggregation
>    Affects Versions: 3.1.0
>         Environment: HDP 3.1.0.78
>  
>            Reporter: agoodboy
>            Priority: Major
>   Original Estimate: 24h
>  Remaining Estimate: 24h
>
> Env: hdp 3.1.0.0-78
> Command: yarn logs -applicationId xxx, throws an error "Not a valid BCFile.", and then exit.
> After open debug log using "export YARN_ROOT_LOGGER="DEBUG,console", and rerun command. It shows that "fileName=/data1/app-logs/hadoop/logs/application_1566555356033_0032/meta" is not a valid BCFile. And after I remove the file from hdfs, and rerun command, it success. 
> So, how to generate this meta file? 
> I guess that is because this in yarn-site.xml:
> <property>
>  <name>yarn.timeline-service.generic-application-history.save-non-am-container-meta-info</name>
>  <value>true</value>
>  </property>
> I set this value to true because I want to see all container logs in timeline web page, orelse I can just see the am container log.
> So, it seems that yarn logs can't properly handle this suituation.
