[BUG] SLF4J: Failed to load class `"org.slf4j.impl.StaticLoggerBinder"`

[LHozzan]

Describe the bug
On fresh start OpenSearch are generated the lines:

main {"type": "logging", "timestamp": "2023-03-06T11:57:13,242Z", "level": "WARN", "component": "stderr", "cluster.name": "opensearch", "node.name": "os-datanode-0", "message": "SLF4J: Failed to load class \"org.slf4j.impl.StaticLoggerBinder\"." }
main {"type": "logging", "timestamp": "2023-03-06T11:57:13,244Z", "level": "WARN", "component": "stderr", "cluster.name": "opensearch", "node.name": "os-datanode-0", "message": "SLF4J: Defaulting to no-operation (NOP) logger implementation" }
main {"type": "logging", "timestamp": "2023-03-06T11:57:13,244Z", "level": "WARN", "component": "stderr", "cluster.name": "opensearch", "node.name": "os-datanode-0", "message": "SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details." }

But OpenSearch working fine.

To Reproduce
Just start OpenSearch instance and check log.

Expected behavior
The warning lines not be generated. It is confusing looking to warnings and OpenSearch works fine.

Host/Environment (please complete the following information):

• K8s (v1.24.4)
• AWS, Kind

Additional context
I found question in the forum, but not be answered.
