JCL vs SLF4J

[Devaraj Das]

Came across this link: http://www.slf4j.org/index.html. Got me interested
since it makes a remark "SLF4J suffers from none of the class loader
problems or memory leaks observed with Jakarta Commons Logging (JCL).". Is
it true that the version of commons-logging we use in hadoop could have
issues to do with memory leaks? If so, we should consider moving to SLF4J
unless there are other issues. There is a well-defined migration path -
