------------------------------
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.
