我已经通过简单的安装设置安装了DataStax Enterprise。我正在尝试使用Cassandra，因此我使用以下命令启动了服务器：
bin/dse cassandra
但它显示出错误。下面是运行上述命令后得到的数据:(还有system.log文件内容）

我遇到了同样的问题......如果你单独安装Spark，请删除（取消设置SPARK_HOME变量），然后尝试重新启动它应该可行。 让我们知道它是怎么回事。
答案 1 :(得分：0)
如果将其作为服务
安装，则将其作为service dse start启动
否则，您的yaml文件[/home/ishan/dse/resources/cassandra/conf/cassandra.yaml]
您是否也想启动Spark？否则在/etc/default/dse中进行更改并设置SPARK_ENABLED=0
