Question

我在solrCloud模式下使用solr 4.10.3。我有一个碎片和3个复制品。正在使用的外部动物园管理员合奏。我在一个索引中的文档增加了太多。现在我想创建更多分片。我尝试使用

http://localhost:8983/solr/admin/collections?action=SPLITSHARD&collection=collection1&shard=shard1

但它会出现以下错误

Error executing split operation for collection: collection1 parent shard: shard1

问题在哪里？它的灵魂是什么？
