Hello,
I'm having an issue getting the master to replicate its index to the slave.
Below you will find my configuration settings. Here is what is happening: I can
access the replication dashboard for both the slave and master and I can
successfully execute HTTP commands against both of these urls through my
browser. Now, my slave is configured to use the same URL as the one I am using
in my browser when I query the master, yet when I do a tail -f <tomcat
home>/logs/catalina.out on the slave server all I see is :
Master - server1.xyz.com Aug 27, 2009 12:13:29 AM org.apache.solr.core.SolrCore
execute
INFO: [] webapp=null path=null params={command=details} status=0 QTime=8
Aug 27, 2009 12:13:32 AM org.apache.solr.core.SolrCore execute

For some reason, the webapp and the path is being set to null and I "think"
this is affecting the replication?!? I am running Solr as the WAR file and it's
1.4 from a few weeks ago.
<requestHandler name="/replication" class="solr.ReplicationHandler" >
<lst name="master">
<!--Replicate on 'optimize'. Other values can be 'commit', 'startup'.
It is possible to have multiple entries of this config string-->
<str name="replicateAfter">optimize</str>
<!--Create a backup after 'optimize'. Other values can be 'commit',
'startup'. It is possible to have multiple entries of this config string .note
that this is just for backup. Replication does not require this -->
<str name="backupAfter">optimize</str>
<!--If configuration files need to be replicated give the names here,
separated by comma -->
<!--<str name="confFiles">schema.xml,stopwords.txt,elevate.xml</str>-->
</lst>
</requestHandler>
Notice that I commented out the replication of the configuration files. I
didn't think this is important for the attempt to try to get replication
working. However, is it good to have these files replicated?
Slave - server2.xyz.com
<requestHandler name="/replication" class="solr.ReplicationHandler" >
<lst name="slave">
<!--fully qualified url for the replication handler of master . It is
possible to pass on this as a request param for the fetchindex command-->
<str
name="masterUrl">http://server1.xyz.com:8080/jdoe/replication</str>
<!--Interval in which the slave should poll master .Format is HH:mm:ss
. If this is absent slave does not poll automatically.
But a fetchindex can be triggered from the admin or the http API -->
<str name="pollInterval">00:00:20</str>
<!-- THE FOLLOWING PARAMETERS ARE USUALLY NOT REQUIRED-->
<!--to use compression while transferring the index files. The possible
values are internal|external
if the value is 'external' make sure that your master Solr has the
settings to honour the accept-encoding header.
see here for details http://wiki.apache.org/solr/SolrHttpCompression
If it is 'internal' everything will be taken care of automatically.
USE THIS ONLY IF YOUR BANDWIDTH IS LOW . THIS CAN ACTUALLY SLOWDOWN
REPLICATION IN A LAN-->
<str name="compression">internal</str>
<!--The following values are used when the slave connects to the master
to download the index files.
Default values implicitly set as 5000ms and 10000ms respectively. The
user DOES NOT need to specify
these unless the bandwidth is extremely low or if there is an
extremely high latency-->
<str name="httpConnTimeout">5000</str>
<str name="httpReadTimeout">10000</str>
<!-- If HTTP Basic authentication is enabled on the master, then the
slave can be configured with the following -->
<str name="httpBasicAuthUser">username</str>
<str name="httpBasicAuthPassword">password</str>
</lst>
</requestHandler>
Thanks for your help!
