nandakumar131 opened a new pull request, #7843: URL: https://github.com/apache/ozone/pull/7843
## What changes were proposed in this pull request? Change log level in `SCMNodeManager#getNodesByAddress` to debug. `SCMNodeManager#getNodesByAddress` is called from `BlockProtocolServer#allocateBlock` and `BlockProtocolServer#sortDatanodes`, in both the cases the client could be running on a node that's not a datanode. Because of this the SCM log file is flooded with `Cannot find node for address` messages. ``` 2025-01-14 13:36:23,602 WARN [IPC Server handler 79 on 9863]-org.apache.hadoop.hdds.scm.node.SCMNodeManager: Cannot find node for address 172.xx.x.151 2025-01-14 13:36:23,602 WARN [IPC Server handler 78 on 9863]-org.apache.hadoop.hdds.scm.node.SCMNodeManager: Cannot find node for address 172.xx.x.152 2025-01-14 13:36:23,614 WARN [IPC Server handler 18 on 9863]-org.apache.hadoop.hdds.scm.node.SCMNodeManager: Cannot find node for address 172.xx.x.152 2025-01-14 13:36:23,614 WARN [IPC Server handler 32 on 9863]-org.apache.hadoop.hdds.scm.node.SCMNodeManager: Cannot find node for address 172.xx.x.151 2025-01-14 13:36:23,614 WARN [IPC Server handler 18 on 9863]-org.apache.hadoop.hdds.scm.node.SCMNodeManager: Cannot find node for address 172.xx.x.152 2025-01-14 13:36:23,614 WARN [IPC Server handler 78 on 9863]-org.apache.hadoop.hdds.scm.node.SCMNodeManager: Cannot find node for address 172.xx.x.115 2025-01-14 13:36:23,614 WARN [IPC Server handler 42 on 9863]-org.apache.hadoop.hdds.scm.node.SCMNodeManager: Cannot find node for address 172.xx.x.140 2025-01-14 13:36:23,614 WARN [IPC Server handler 67 on 9863]-org.apache.hadoop.hdds.scm.node.SCMNodeManager: Cannot find node for address 172.xx.x.152 2025-01-14 13:36:23,614 WARN [IPC Server handler 71 on 9863]-org.apache.hadoop.hdds.scm.node.SCMNodeManager: Cannot find node for address 172.xx.x.117 2025-01-14 13:36:23,614 WARN [IPC Server handler 34 on 9863]-org.apache.hadoop.hdds.scm.node.SCMNodeManager: Cannot find node for address 172.xx.x.152 2025-01-14 13:36:23,614 WARN [IPC Server handler 12 on 9863]-org.apache.hadoop.hdds.scm.node.SCMNodeManager: Cannot find node for address 172.xx.x.151 ... ``` We don't have to log a WARN message for this case, we can change this is DEBUG message. This will reduce the log file size and make it easier to debug other issues. ## What is the link to the Apache JIRA HDDS-12292 ## How was this patch tested?
