What changes were proposed in this pull request?
To change the default loglevel of the 'Negative usedBytes' message in Recon from WARN to DEBUG.
In Recon, WARN messages of the type:
2025-05-13 12:41:29,141 WARN [ContainerSizeCountTask]-org.apache.hadoop.ozone.recon.tasks.ContainerSizeCountTask: Negative usedBytes (-99999999) for container #555555 treating it as 0
Can flood the logs in large clusters. In a cluster with 150+ DataNodes and 50+ PB of data, I observed 90k such entries reporting once per minute, flooding the Recon logs into uselessness.
These messages are originally logged on the DataNode, and then are thrown in Recon from the ContainerSizeCountTask. The problem driving the messages on the DataNode side has been resolved in HDDS-11267. The flood of messages on the Recon side can be resolved by switching the loglevel of this message from WARN to DEBUG.
Recon already captures this information in the UI, so the information remains aggregated for the user, without repeating the WARN messages every minute.
