Hi,

Can someone please help me and let me know what I did wrong or am I missing something?

[root@sandbox ~]# yarn log -applicationId application_1614345689259_0002
Picked up _JAVA_OPTIONS: -Xmx2048m -XX:MaxPermSize=512m -Djava.awt.headless=true
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0
Error: Could not find or load main class log
[root@sandbox~]#

Thanks,

Hello @ryu

The command that you are using is incorrect or maybe a typo. There is a 's' missing after log in the command.

Use below command to fetch the logs.

Yarn logs -applicationId <application id of the job>

Please accept this answer if you find it useful to resolve your issue.
