> for `org.apache.hadoop` classes to only log WARN
+1
Regarding the warning about missing appenders: I've also seen it but only in
the logs of the ApplicationMaster and nevertheless the `syslog` file contains
log messages obviously written via log4j. So, I don't know whether it's an
issue at all and esp. for us because in the ApplicationMaster no Nutch classes
are involved.
> Does HADOOP-12956 stop us from implementing this
I do not think so. But looks like the upgrade has no effect in
(pseudo)distributed mode and the log4j.properties in `$HADOOP_HOME/etc/hadoop/`
(or `/etc/hadoop/conf/`) takes precedence.
