For posterity...
After reading through http://wiki.apache.org/solr/SolrConfigXml and
http://wiki.apache.org/solr/CoreAdmin and
http://issues.apache.org/jira/browse/SOLR-646, I think there's no way
for me to make only one core specify &shards=foo, short of duplicating
my solrconfig.xml for that core and adding one line:
- I can't use a variable like ${shardsParam} in a single shared
solrconfig.xml, because the line
<str name="shards">${shardsParam}</str>
has to be in there, and that forces a (possibly empty) &shards
parameter onto cores that *don't* need one, causing a
NullPointerException.
- I can't suck in just that one <str> line via a SOLR-646-style import, like
#solrconfig.xml
<requestHandler>
<lst name="defaults">
<import file="${shardspec_file}"/>
</list>
</requestHandler>
#solr.xml
<core name="core0"><property name="shardspec_file" value="some_file"/>...
<core name="core1"><property name="shardspec_file" value="/dev/null"/>...
because SOLR-646's <import> feature got cut.
So I think my best bet is to make two mostly-identical
solrconfig.xmls, and point core0 to the one specifying a &shards=
parameter:
<core name="core0" config="core0_solrconfig.xml"/>
I don't like the duplication of config, but at least it accomplishes my goal!
