Ok, thank you. I did the following steps.

1. Started an external zookeeper
2. Copied a conf-directory to zookeeper: 
bin/solr zk upconfig -n books -d $HOME/solr-6.5.1/server/solr/tommy/conf -z 
localhost:2181
// This is a conf-directory from a standalone solr when dataimport was working!
--> Connecting to ZooKeeper at localhost:2181 ...
Uploading <....> for config books to ZooKeeper at localhost:2181
// I think no errors, but how can I check it in zookeeper? I found no files 
solrconfig.xml ...
in the zookeeper directories (installation dir and data dir)
3. Started solr:
bin/solr start -c
4. Created a books collection with 2 shards
bin/solr create -c books -shards 2

Result: I see in the web-ui my books collection with the 2 shards. No errors so 
far.
However, the Dataimport-entry says:
"Sorry, no dataimport-handler defined!"

What could be the reason?
