Erik Hatcher commented on SOLR-637:
-----------------------------------
The solr.data.dir technique _should_ be supported by the multicore.xml as well.
Maybe it is a misunderstanding of how -Dsolr.data.dir works? It works by
having a ${solr.data.dir} or ${solr.data.dir:<default value>} spelled out in
any of the config files, even schema.xml. So I believe it should work to be
able to craft a multicore.xml as follows:
<multicore adminPath="/admin/multicore" persistent="true" >
<core name="core0" instanceDir="${root.dir}/core0" />
<core name="core1" instanceDir="${root.dir}/core1" />
</multicore>
And launch with -Droot.dir=whatever
Could you confirm whether that works for you? Of course the value of the
<dataDir> in each of your core's solrconfig.xml is taken into consideration
also.
[I've not confirmed what I'm typing here, just tossing out how I think it
currently works - please confirm]
