This directory contains shell scripts which provided the original replication & backup functionality dating back to Solr 1.1. These scripts only work on systems that support removing open hard links and were superseded by the ReplicationHandler in Solr 1.4. These scripts are no longer actively maintained, improved, or tested, but they have been left in the source tree for use by legacy users who are satisfied with their basic functionality. For more information on how these scripts can be used, please consult the wiki... https://wiki.apache.org/solr/CollectionDistribution
