> Project: Solr

> Affects Versions: 1.4.1
> Reporter: Bill Bell
> Fix For: 1.4.2

> Attachments: ping.jsp

>
> When hosting SOLR at Amazon there is an issue with load balancing and
> replication. This is especially useful when you are using multiple slaves
> behind
> the load balancer and a MASTER SOLR box. The Load Balancer at Amazon has no
> way of knowing that each SLAVE has data from the MASTER replicated. As soon
> as the instance starts,
> Amazon starts sending requests to the Slaves. You need to have the Slave
> running in order to get the files from the Master.
> The solution is to add a ping.jsp page that Amazon hits on the Slave
> Tomcat/Jetty instances. The ping.jsp checks all cores to make sure they all
> have data, otherwise it returns a non-200 values which signals Amazon
> to not send requests to the Slaves.
> Put this into your solr.war file as /admin/replication/ping.jsp
