thank u for replying very much . in fact ,we make a process for this problem , we found when master building index, it will clean self index when building index . so slave every minute to sync index, destroy self index folder.
by the way : we building index using dataimport0?command=full-import&clean=false ,dataimport1?command=full-import&clean=false, dataimport2?command=full-import&clean=false . when i using in solr3.6 has no problem ,never delete at first . does solr 4 need to special config anything ? thanks a lot . -- View this message in context: http://lucene.472066.n3.nabble.com/problems-about-solr-replication-in-4-3-tp4079665p4080480.html Sent from the Solr - User mailing list archive at Nabble.com.
