Hi Erik,

about 1>
I have no core.properties at all, just a clean new installation.
- 5 x Zookeeper on 5 different server
- 5 x Solr 6.5.1 on 5 different server
- uploaded a configset with "bin/solr zk upconfig ..."
- started first Solr node with port 8983 of first server
- started second Solr node with port 7574 of first server
No core, no cluster, no collection, no nodes.

about 2>
Sysvars just JAVA_HOME in .bashrc and in solr.in.sh SOLR_JAVA_HOME,
SOLR_STOP_WAIT, SOLR_HEAP, ZK_HOST, SOLR_HOST


I tried "bin/solr -e cloud" and have in example/cloud/node1/ and node2/
separate logs directories for each node. So I thought of a misconfig
at my fresh clean Solr installation.
But if there is no core or node jet it makes sense to write logs into
a general single directory, but don't move existing logs to archived.

Regards,
Bernd
