大家好:我是SOLR的新手,我正在尝试在相当复杂的代码库中解决部署失败问题。
我当然需要立即理解这个错误:
org.apache.solr.common.SolrException:执行CREATE的默认实现时出错
Error executing default implementation of CREATE
request: http://localhost:8983/solr/admin/cores?action=CREATE&name=tmp_xxxx_count_abc&instanceDir=/tmp/solr_indexes_re/viewbuilder_pckg100121/myDataDirectory/part-00000&wb=javabin&version=2
但一般来说,我有一个长期目标是从这个问题中学习:
1)一般情况下:在调试SOLR应用程序时,如何确定客户端上的错误,服务器上的错误?我是否应该研究可靠,有用的面向用户的日志?
2)在运行“CREATE”的“默认实施”时,SOLR的投诉是什么意思?这会引发任何直接恐惧吗?
3)我开始注意到,有时候,当内存不足时,SOLR写鳕鱼会抛出一些奇怪的错误信息,例如它无法获得锁定。 - 运行/调试SOLR客户端和解释错误消息是否有一些不成文的基本规则?
编辑有关堆叠痕迹的更多细节:
在终端中,我也看到了服务器端堆栈跟踪:
