Solr 1.4.1. So, from the documentation at
http://wiki.apache.org/solr/SolrReplication
I was wondering if I could get away without having any actual
configuration in my slave at all. The replication handler is turned on,
but if I'm going to manually trigger replication pulls while supplying
the master URL manually with the command too, by:
command=fetchIndex&masterUrl=$solr_master
Then I was thinking, gee, maybe I don't need any slave config at all.
That _appears_ to not be true. In such a situation, when I tell the
slave to fetchIndex&masterUrl=$solr_master, the command gives a 200 OK.
But then I go and check /replication?command=details on the slave, I'm
actually presented with an exception:
message null java.lang.NullPointerException at
org.apache.solr.handler.ReplicationHandler.isPollingDisabled(ReplicationHandler.java:412)
at
So I'm thinking this is probably becuase you actually can't get away
with no slave config at all.
So:
1) Is this a bug? Maybe I did something I shoudn't have, but having
command=details report a NullPointerException is probably not good,
right? If someone who knows better agrees, I'll file it in JIRA?
2) Does anyone know what the minimal slave config is? If I plan to
manually trigger replication pulls, and supply the masterUrl.... maybe
just an empty <lst name="slave"></lst>. Or are there other parameters I
have to set even though I don't plan to use them? (I do not want
automatic polling, only manually triggered pulls). Anyone have any
advice, or should I just trial and error?
