Question

我正在使用wso2bam-2.4.0和外部apache-cassandra-2.0.2。

我用java选项运行wso2：

-Ddisable.cassandra.server.startup=true \

当我执行任何“insert overwrite table ....”时，会发生以下错误：

好像你的cassandra集群没有正确连接BAM服务器。确保在Hive脚本中正确提及您的凭据和IP /端口等。或者您可以在master-datasource.xml中正确提及它们。如果一切正确，请尝试使用Cassandra 1.x版本。

WSO2 BAM无法在分析脚本上加载子/比较器
