6.8. Logging ConfigurationΒΆ

Each GeoMesa Tools distribution comes bundled by default with an SLF4J logging implementation that is installed to the lib directory named slf4j-log4j12-1.7.5.jar. If you already have an SLF4J implementation installed on your Java classpath you may see errors at runtime and will have to exclude one of the JARs. This can be accomplished by simply deleting the bundled slf4j-log4j12-1.7.5.jar.

Note that if no SLF4J implementation is installed you will see this error:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

In this case you may download SLF4J here. Extract slf4j-log4j12-1.7.5.jar and place it in the lib directory of the binary distribution. If this conflicts with another SLF4J implementation, you may need to remove it from the lib directory.
