Solr 4 主机端口和上下文信息（ZooKeeper Base URL）设置

Question

我正在尝试从 Solr 4-Beta 升级到 Solr 4。在使用 Solr 4-beta 时，我在 Solr.xml 文件中配置了主机和端口号，如下所示，一切正常。

<solr persistent="true">
  <cores host="xxx.xx.x.xxx" adminPath="/admin/cores" hostPort="8180" hostContext="solr4" sharedLib="lib">
  </cores>
</solr>

但是当我升级到 Solr 4.0 时，ZooKeeper 基本 URL 被设置为“http://Computer-name:8983/Solr”，这在联系其他节点时会引发以下异常。由于某种原因，ZooKeeper 初始化没有从 Solr.xml 中选择主机和端口信息，而是获取默认的 Solr 端口和上下文信息。有人可以帮忙纠正这个 ZooKeeper 的 base_url 吗？

您的 solr.xml 配置看起来不错。除了sharedLib="lib"，sharedLib 属性都属于标签<solr persistent="true" sharedLib="lib">。

异常Caused by: java.net.UnknownHostException: COMPUTER-NAME

请确保以下几点：

1) zkHost 参数中提供的 ZooKeeper 主机名映射到 hosts 文件中

-DzkHost=COMPUTER-NAME:2181,localhost:2182,localhost:2183

主机文件定义

127.0.0.1    localhost
xxx.xxx.xxx.xxx     COMPUTER-NAME

2) 更新了solr.xml 出现在SOLR_HOME 的正确路径中
