Solr完全导入多核



我正在尝试创建一台具有多个核心的Solr机器。目前,我的问题是执行初始的完全导入。第一个核心完全进口。然而,当我尝试导入第二个核心时,我得到了以下错误:

这种情况发生在第二个核心上,不管我从哪个核心开始。我在这里错过了什么?每个核心都能完美地独立运行。

这是因为两个核心的索引目录相同。一旦您开始对一个核心进行完全导入,该目录中就会有一个write.lock文件,在导入完成之前,该文件不会被删除。无论如何,您都希望将核心的索引保存在单独的目录中,因此修改solrconfig.xml如下:
  <!-- Used to specify an alternate directory to hold all index data
       other than the default ./data under the Solr home.
       If replication is in use, this should match the replication 
       configuration. -->
  <dataDir>./data/${solr.core.name}</dataDir>
