Invalid Version when slave node pull replication from master node

[YouPeng Yang]

HI solrusers

   I'm testing the replication within SolrCloud .
   I just uncomment the replication section separately on the master and
slave node.
   The replication section setting on the  master node:
    <lst name="master">
         <str name="replicateAfter">commit</str>
         <str name="replicateAfter">startup</str>
         <str name="confFiles">schema.xml,stopwords.txt</str>
       </lst>
 and on the slave node:
  <lst name="slave">
         <str name="masterUrl">http://10.7.23.124:8080/solr/#/</str>
         <str name="pollInterval">00:00:50</str>
   </lst>

   After startup, an Error comes out on the slave node :
80110110 [snapPuller-70-thread-1] ERROR org.apache.solr.handler.SnapPuller
?.Master at: http://10.7.23.124:8080/solr/#/ is not available. Index fetch
failed. Exception: Invalid version (expected 2, but 60) or the data in not
in 'javabin' format


 Could anyone help me to solve the problem ?
