Hi,
I wanted to move to log4j2 as the logging implementation for Solr (1) but ran into some issues when I switched out the appropriate jars. Unfortunately there are a few classes that directly rely on log4j to be on the classpath instead and don't use the slf4j logging facade. So I wanted to remove these references 1. org.apache.solr.core.ZkContainer https://github.com/apache/lucene-solr/blob/trunk/solr/core/src/java/org/apache/solr/core/ZkContainer.java#L218 I don't know the impact of this change, but shouldn't this call ``org.apache.solr.logging.MDCLoggingContext.clear()` ? 2. org.apache.solr.handler.component.RangeFacetProcessor and org.apache.solr.handler.component.RangeFacetRequest use log4j instead of slf4j to get logger I had a stab at it at https://github.com/oschrenk/lucene-solr/commit/025b4802caf0360c63a3554af82e9ed4c94ff5a3#diff-7d822e8ff8ff21d88437652bbc894739R28 Cheers, Oliver (1) http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201507.mbox/%3C0F4200AE-3D7E-40FE-B0C2-040E89BBA58B%40elmar.nl%3E <http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201507.mbox/%[email protected]%3E>
