Configuring the Solr library path 

Workaround for DSE Search failure to find files in directories that are defined by the <lib> property.

Contrary to the examples shown in the solrconfig.xml file that indicate support for relative paths, DataStax Enterprise does not support the relative path values that are set for the <lib> property. DSE Search fails to find files in directories that are defined by the <lib> property. The workaround is to place custom code or Solr contrib modules in the Solr library directories.

The default Solr library path location depends on the type of installation:
Installer-Services /usr/share/dse/resources/solr/lib
Package installations /usr/share/dse/solr/lib
Installer-No Services and Tarball installations install_location/resources/solr/lib
