Replicating files containing external file fields

[Arun Rangarajan]

>From https://wiki.apache.org/solr/SolrReplication I understand that index
dir and any files under the conf dir can be replicated to slaves. I want to
know if there is any way the files under the data dir containing external
file fields can be replicated. These are not replicated by default.
Currently we are running the ext file field reload script on both the
master and the slave and then running reloadCache on each server once they
are loaded.
