solrCloud新建core或collection失败报Caused by: solr.DataImportHandler错误

问题的出现：

       在solrCloud的schema.xml文件需要更改时，由于配置文件是放在zookeepr中的，所以需要conf文件重新上传进conf，在我重新上传conf之后，出现了一下问题。

Tomcat的solr页面出现全页面错误提示：

      这是由于我没有删除zookeepr中collections下的collection1配置文件以及各solrhome下的collection1的配置，我删除之后，重启tomcat，进入solr正常，然后出现第二个问题，

http://192.168.25.154:8080/solr/admin/collections?action=CREATE&name=technology&numShards=1&replicationFactor=3

    在使用以上命令创建collection时，返回的信息是 failure 提示是

Unable to create collection [technology] Caused by: solr.DataImportHandler

解决办法：           

    出现错误的原因是我向zookeepr中传的是

solr-4.10.3\example\example-DIH\solr\solr\conf

    这个路径下的conf文件，

    而正确的应该是这个路径下的conf

solr-4.10.3\example\solr\collection1\conf

   具体原因还未知，有待探究。希望有会的大神能告知，感激不尽。
