交换核心（Reindex - > Live）我的从机器腐败了

StackOverflow https://stackoverflow.com//questions/9685016

题

我在这里有一个非常奇怪的问题，我已经设置了我的solr架构，因为我认为 here 并且一切正常，除了我的solr从机器损坏。 （测试）设置如下：

solr设置

  • 一个有两个核心（Reindex和Live）的索尔大师
  • 一个有两个核心（Reindex和Live）的索尔奴隶（Reindex和Live）
  • pollinterval设置为00:00:02
  • 优化或提交后复制
  • 在Ubuntu（11.10）版本1.4.0下运行solr。

过程

整个过程如此：

  1. 我们擦除主reindex核心的索引
  2. we 禁用复制
  3. 我们启动DataImportHandler在10.000文档的PEICE中导入MySQL数据（以防止Long MySQL锁定）
  4. afther the dataimporthandler完成了（400万条记录），我们可以在主站中进行复制
  5. 从大师
    6. 获取新的reindex核心
  6. 一次获取完成通过查看'isReplicating'属性我们发出一个核心交换

    7. 让我们假设实时核心在完全重建后有5000个文档和reindex核心20000。

    （错误）结果

    交换后，这是结果：

    硕士：Live（20000），Reindex（5000） 奴隶：Live（20000），Reindex（20000）

    它看起来是从站将他的reidex核心复制到实时核心，但不会与master等reindex核心交换实时核心。问题是我猜从奴隶认为它是较新的，然后是reindex核心的master和结果是复制。

    以下是发出交换后的一些日志消息：

    直到步骤6如果我手动完成所有事情，一切都可以。核心交换后的一切都勾结。

    我希望有人可以帮助我或告诉我我做错了什么..如果你做核心交换时，应该禁用复制吗？任何提示？

有帮助吗？

解决方案

我设法解决了这个问题，问题是我的两个核心都使用了相同的数据。通过将Solr.xml文件中的Datadir设置为两个不同的目录解决了问题！
