通常你需要先找到IP地址,但是aztk可以通过ssh命令轻松找到它: aztk spark cluster ssh--id mysparklyr4 (如果你在步骤5中设置了密码,你需要在这里提供一个密码。)这会在头节点上给你一个shell,但更重要的是它映射了Spark和RStudio服务器的端口,这样你就可以连接到他们http://localhost在下一步中使用URL。在完...

通过适当的计划,可以设计集群有弹性以应对许多常见问题,例如单个节点的丢失或网络连接丢失,甚至区域范围内的断电(例如断电)。 您可以使用 cross-cluster replication 将数据复制到远程跟随者集群,该跟随者集群可能与领导者集群位于不同的数据中心,甚至位于不同的大陆。跟随者群集充当热备用服务器,在灾难严重到导致领导者...

When running mappings in Spark engine, dynamic allocation can be used to dynamically scale up and down the number of executors based on the stage and its associated tasks. This helps in efficient usage of cluster resources eliminating unnecessary idle processes that may take up resources while awai...
