---------------------------------
Summary: Avoid introducing log4j and slf4j-log4j dependencies for
modules other than hbase-assembly
Key: HBASE-24309
URL: https://issues.apache.org/jira/browse/HBASE-24309
Project: HBase
Issue Type: Sub-task
Reporter: Duo Zhang
In general, a library should not force the down stream users to use a specific
logging framework, and this is why there is a slf4j library.
For HBase, since we also publish the testing-util module which almost depends
on all other sub modules, we should not introduce logging dependencies other
than slf4j-api in these modules. We should only add log4j dependencies in
hbase-assembly and ship it with our binary distribution.
This is also important for switching to log4j2.
