Subject Index Replication Failing in Solr 4.2.1
Date Tue, 09 Apr 2013 15:58:12 GMT
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

In Both Master and Slave The File list for replicable version is correct.
