Hi All, I am migrating from Solr 3.5.0 to Solr 4.2.1. And everything is running fine and set to go, except the master slave replication.
We use master slave replication with multi cores ( 1 master, 10 slaves and 20 plus cores). My Configuration is : Master : Solr 3.5.0, Has existing index, and delta import running using DIH. Slave : Solr 4.2.1 , Has no startup index Apr 9, 2013 9:18:40 PM org.apache.solr.core.SolrCore execute INFO: [phcare] webapp= path=/replication params={command=fetchindex&_=1365522520521&wt=json} status=0 QTime=1 Apr 9, 2013 9:18:40 PM org.apache.solr.handler.SnapPuller fetchLatestIndex *INFO: Master's generation: 107876 *Apr 9, 2013 9:18:40 PM org.apache.solr.handler.SnapPuller fetchLatestIndex *INFO: Slave's generation: 79248 *Apr 9, 2013 9:18:40 PM org.apache.solr.handler.SnapPuller fetchLatestIndex INFO: Starting replication process *Apr 9, 2013 9:18:40 PM org.apache.solr.handler.SnapPuller fetchFileList SEVERE: No files to download for index generation: 107876 *Apr 9, 2013 9:18:40 PM org.apache.solr.core.SolrCore execute INFO: [phcare] webapp= path=/replication params={command=details&_=1365522520556&wt=json} status=0 QTime=7 In Both Master and Slave The File list for replicable version is correct. *on Slave * { - masterDetails: { - indexSize: "4.31 MB", - indexPath: "/var/lib/fk-w3-sherlock/cores/phcare/data/index.20130124235012", - commits: [ - [ - "indexVersion", - 1323961124638, - "generation", - 107856, - "filelist", - [ - "_45e1.tii", - "_45e1.nrm", - ...... *ON Master * [ - "indexVersion", - 1323961124638, - "generation", - 107856, - "filelist", - [ - "_45e1.tii", - "_45e1.nrm", - "_45e2_1.del", - "_45e2.frq", - "_45e1_3.del", - "_45e1.tis", - .......... Can someone help. Our whole Migration to Solr 4.2 is blocked on Replication issue. --- Thanks & Regards Umesh Prasad
