SolrException:内部服务器错误

Question

我正在申请Solr.我正在使用apache-solr-solrj-1.4.0.jar.

当我尝试从中调用add(SolrInputDocument doc)时CommonsHttpSolrServer,我收到以下异常:

org.apache.solr.common.SolrException:org.apache.solr.client.solrj中org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.request(CommonsHttpSolrServer.java:424)的内部服务器错误内部服务器错误. impl.CommonsHttpSolrServer.request(CommonsHttpSolrServer.java:243)位于org.apache.solr.client.solrj.SolrServer.add的org.apache.solr.client.solrj.request.AbstractUpdateRequest.process(AbstractUpdateRequest.java:105) SolrServer.java:64)

有谁可以帮我解决这个问题？

以下是solrconfig.xml中的属性:

<lockType>native</lockType>
<unlockOnStartup>false</unlockOnStartup>
<reopenReaders>true</reopenReaders>

我在solr服务器日志中收到以下异常:

Answer 1

我在我的solrconfig.xml中设置了以下内容并且它可以正常工作.

<lockType>simple</lockType>
<unlockOnStartup>true</unlockOnStartup>

另外,设置以下内容以避免索引目录上的写锁定异常:

<maxFieldLength>10000</maxFieldLength>
<writeLockTimeout>60000</writeLockTimeout>
<commitLockTimeout>60000</commitLockTimeout>

Answer 2

我很不确定，但在这个线程中

http://www.mail-archive.com/solr-user@lucene.apache.org/msg08048.html

他们建议使用

<unlockOnStartup>true</unlockOnStartup>

和

<lockType>simple</lockType>

我认为只要您通过 solr 或 solrj 访问索引（不是通过 lucene！），这应该是安全的。

还有其他想法吗？
