------------------------------

             Summary: yarn logs throws an error "Not a valid BCFile"
                 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


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.
