无法通过Luke编辑Solr字段

Question

我正在使用Luke浏览一些Solr索引，当我试图“重建和编辑”我的文档中的一个浮动字段，然后“删除旧的并添加”时，我得到了一个异常：

java.lang.NullPointerException

没有其他信息告诉我为什么我会得到NullPointerException。我正在对用Solr 3.4创建的一些索引运行最新的Luke3.5。你知道还有什么地方不对劲吗...？

为了安全起见，我停止了Tomcat，并确保可以从运行Luke的用户编辑索引文件(尝试排除问题可能是索引文件上的用户权限问题的情况)

Answer 1

对于Solr/Lucene和Luke，我总是使用完全相同的版本。这一点尤其重要，因为您正在尝试更改Luke中的索引。它可以写出Solr/Lucene无法读取的版本。
