solr replication failing with error: Master at: is not available. Index fetch failed

[geeky2]

hello all,

enviornment: centOS and solr 3.5

i am attempting to set up replication betweeen two solr boxes (master and
slave).

i am getting the following in the logs on the slave box.

2012-04-23 10:54:59,985 SEVERE [org.apache.solr.handler.SnapPuller]
(pool-12-thread-1) Master at:
http://someip:someport/somepath/somecore/admin/replication/ is not
available. Index fetch failed. Exception: Invalid version (expected 2, but
10) or the data in not in 'javabin' format

master jvm (jboss host) is being started like this:

-Denable.master=true

slave jvm (jboss host) is being started like this:

-Denable.slave=true

does anyone have any ideas?

i have done the following:

used curl http://someip:someport/somepath/somecore/admin/replication/ from
slave to successfully see master

used ping from slave to master

switched out the dns name for master to hard coded ip address

made sure i can see
http://someip:someport/somepath/somecore/admin/replication/ in a browser


this is my request handler - i am using the same config file on both the
master and slave - but sending in the appropriate switch on start up (per
the solr wiki page on replication)

    <lst name="master">

      <str name="enable">${enable.master:false}</str>
      <str name="replicateAfter">startup</str>
      <str name="replicateAfter">commit</str>



      <str name="confFiles">schema.xml,stopwords.txt,elevate.xml</str>

      <str name="commitReserveDuration">00:00:10</str>
    </lst>

    <str name="maxNumberOfBackups">1</str>
    <lst name="slave">

      <str name="enable">${enable.slave:false}</str>
      <str
name="masterUrl">http://someip:someport/somecore/admin/replication/</str>

      <str name="pollInterval">00:00:20</str>


      <str name="compression">internal</str>

      <str name="httpConnTimeout">5000</str>
      <str name="httpReadTimeout">10000</str>

    </lst>
  </requestHandler>


any suggestions would be great

thank you,
mark
