Zeppelin:如何在Zeppelin中重新启动sparkContext [英] Zeppelin: How to restart sparkContext in zeppelin

问题描述

我正在使用Zeppelins Spark解释器的隔离"模式，在此模式下，它将为Spark集群中的每个笔记本启动一个新作业.我想在笔记本执行完毕后通过齐柏林飞艇取消工作.为此，我做了sc.stop这停止了sparkContext，并且作业也从spark集群中停止了.但是下一次当我尝试运行笔记本时，它不会再次启动sparkContext.那怎么办呢?

I am using Isolated mode of zeppelins spark interpreter, with this mode it will start a new job for each notebook in spark cluster. I want to kill the job via zeppelin when the notebook execution is completed. For this I did sc.stop this stopped the sparkContext and the job is also stopped from spark cluster. But next time when I try to run the notebook its not starting the sparkContext again. So how to do that?

推荐答案

有点直观，但是您需要访问解释器菜单选项卡，而不是直接停止SparkContext:

It's a bit counter intuitive but you need to access the interpreter menu tab instead of stopping SparkContext directly:

• 转到解释器列表.

• go to interpreter list.

找到Spark解释器，然后单击右上角的重新启动:

find Spark interpreter and click restart in the right upper corner:
