Datastax 5.0.5信息[PO-thread-0] DbInfoRollupPlugin.java - 检索节点级别db摘要时出错

Question

我在2个相同的群集上运行DSE 5.0.5，所有节点都是Spark + SOLR。在第一一切都很好，但是在第二我在/var/lib/cassandra/system.log此消息：

INFO [PO-thread-0] 2017-04-02 19:26:43,176 DbInfoRollupPlugin.java:196 - Error retrieving node level db summary 

据悉为“INFO”但是什么是错的，我不能想办法。部分堆栈跟踪如下：

您能指出要检查什么来纠正此问题。 非常感谢

我想通了，是这样的特性是：有3000毫秒的默认

dse.db_info_rollup_node_query_timeout。

但是我不知道在哪里设置？

PLS咨询，

Answer 1

请设置在dse.yamlperformance_core_threads: 2。请注意，此设置可能缺少默认dse.yaml，因此您必须添加它。不要将它与

混淆虽然您收到该超时异常，它应该工作。
