Yes I am referring to the dataimport tab in the admin UI and issue SOLR-10035. My previous setup w/ 6.3 did not show this error. I then upgraded to 7.1.0 and the error shows. I upgraded(downgraded) to versions 6.5.0 and 6.6.2 and I do not see the error. Version 7.0.1 also shows the error for me. I am currently using version 6.6.2 and have been successfully able to run a data import from the admin UI.
In my config directory we have solcore.properties solrconfig.xml which defines the dataimport handler (data-config.xml) schema.xml dataimport.properties data-config.xml some admin-extra*.html files We copy all the config files over to the slave instances and they do no show this behavior on 7.1.0, dataimport tab loads fine. The only thing I notice is on the slaves I see entries like this in the log: 2017-11-07 13:36:11.200 INFO (qtp2053591126-35) [ x:solr_aggregate_production] o.a.s.c.S.Request [solr_aggregate_production] webapp=/solr path=/admin/mbeans params={cat=QUERY&wt=json&_=1510061783971} status=0 QTime=0 vs on the master that shows the error. 2017-11-07 13:29:14.131 INFO (qtp1839206329-36) [ x:solr_aggregate_production] o.a.s.c.S.Request [solr_aggregate_production] webapp=/solr path=/admin/mbeans params={cat=QUERYHANDLER&wt=json&_=1510061366718} status=0 QTime=2 I see just "QUERY" in the slave that is working and "QUERYHANDLER" in the master that isn't. This is why I referenced the issue w/ 6.4 (SOLR-10035). Other than that I do not see anything in the log showing and error for the dataimport handler.
