Hello,I just upgraded to 4.1 and my 4.0 multicore setup immediately stopped booting. I fixed apache-* prefix changes, but have another one that is more weird. Basically, I have two cores with lib sections in their solrconfig.xml (running from example dir with custom solr.solr.home). First core: <lib dir="${user.dir}/../contrib/analysis-extras/lucene-libs/" /> <lib dir="${user.dir}/../contrib/analysis-extras/lib/" /> Second core: <lib dir="${user.dir}/../dist/" regex="solr-cell-\d.*\.jar" /> <lib dir="${user.dir}/../contrib/extraction/lib" regex=".*\.jar" /> When I run both cores, the first core fails to load as it cannot find ICUFoldingFilterFactory org.apache.solr.common.SolrException: Plugin init failure for [schema.xml] fieldType "email": Plugin init failure for [schema.xml] analyzer/filter: Error loading class 'solr.ICUFoldingFilterFactory' at org.apache.solr.util.plugin.AbstractPluginLoader.load(AbstractPluginLoader.java:177) at org.apache.solr.schema.IndexSchema.readSchema(IndexSchema.java:369) at org.apache.solr.schema.IndexSchema.<init>(IndexSchema.java:113) at org.apache.solr.core.CoreContainer.createFromLocal(CoreContainer.java:1000) .... If I remove lib directives from the second core, the first core boots fine (second one of course does not). Even stranger, I can add first core's libraries to the second core's and the first core starts working again. Looks like a serious regression. But I can't imagine what it could be connected to. Should I open JIRA or can somebody sanity check this for me first?
That does sound like a bug. I am not sure, though. Here's a possible workaround:
Put all your extra jars in a lib directory under your solr.home (where the solr.xml that describes your cores goes). Then add sharedLib="lib" option to the solr tag of your solr.xml. If there is already a lib directory here for radically different purposes (jetty, for example), call the new directory something else like solr-lib and reference appropriately in the sharedLib option.
I am using this method to load the ICU jars into my 4.1 SolrCloud. Thanks, Shawn
