我们正在尝试在连接到 Vora 的两个 Spark 控制器之间进行负载平衡......
我们能够连接并将查询发送到控制器。当结果应该被传递回hana时,就会出现问题,进程挂起并且永远不会完成。
日志状态的最后几行:
17/02/14 14:24:12 INFO CommandRouter$$anon$1: Created broadcast 7 from executeSelectTask at CommandRouter.scala:650
17/02/14 14:24:12 INFO CommandRouter$$anon$1: Starting job: executeSelectTask at CommandRouter.scala:650
17/02/14 14:24:12 INFO CommandRouter$$anon$1: Created broadcast 8 from broadcast at DAGScheduler.scala:1008
17/02/14 14:24:14 INFO CommandRouter$$anon$1: Created broadcast 9 from broadcast at DAGScheduler.scala:1008
是否有特定的配置允许在两个控制器之间进行负载平衡?
