log4j + after setting DEBUG mode level , logs still display as INFO

Question

we configured the log4j of the resource manger service to be as DEBUG mode as the following

yarn.server.resourcemanager.appsummary.logger=DEBUG,RMSUMMARY

and then we restart the resource manger service ( from ambari dashboard )

from the logs we still saw the log level as INFO instead to be DEBUG

example:

2021-07-02 06:00:53,620 INFO  resourcemanager.ResourceTrackerService (ResourceTrackerService.java:registerNodeManager(458)) - NodeManager from node worker02.bd-gontamopigure-1.com(cmPort: 45454 httpPort: 8042) registered with capability: <memory:16384, vCores:3>, assigned nodeId worker02.bd-gontamopigure-1.com:45454
2021-07-02 06:00:53,620 INFO  rmnode.RMNodeImpl (RMNodeImpl.java:handle(440)) - worker02.bd-gontamopigure-1.com:45454 Node Transitioned from NEW to RUNNING
2021-07-02 06:00:53,621 INFO  capacity.CapacityScheduler (CapacityScheduler.java:addNode(1364)) - Added node worker02.bd-gontamopigure-1.com:45454 clusterResource: <memory:32768, vCores:6>

so I share the log4j configuration

any idea what is wrong with:

yarn.server.resourcemanager.appsummary.logger=DEBUG,RMSUMMARY

and why we get INFO inspite we configured DEBUG

here all log4j configuration

Answer 1

Read about log levels.

for example if you set DEBUG you will see all INFO, ERROR, WARN and so on.

See the below picture from this post.

If you don't want to see INFO set your log level to WARN.
