bq.  Did anyone file a bug with Hadoop? Will the upgrade to Hadoop3 in 
SOLR-9515 help?

HADOOP-12956 should be the Jira that's tracking it on the hadoop side of

> The logging services project has officially announced the EOL of log4j 1:
> https://blogs.apache.org/foundation/entry/apache_logging_services_project_announces
> In the official binary jetty deployment, we use use log4j 1.2 as our final 
> logging destination, so the admin UI has a log watcher that actually uses 
> log4j and java.util.logging classes.  That will need to be extended to add 
> log4j2.  I think that might be the largest pain point to this upgrade.
> There is some crossover between log4j2 and slf4j.  Figuring out exactly which 
> jars need to be in the lib/ext directory will take some research.
