how to change spark.r.backendConnectionTimeout value?

When I use R in Zeppelin it works but when I leave the Zeppelin running one day, next day I get this error for R only:

sparkR backend is dead, please try to increase spark.r.backendConnectionTimeout

I see from the Spark configuration that default value is set to 6000 seconds. Does anybody know how to change this value and what value would be useful to keep Zeppelin running all the time? I can use other interpreters (Python, Jdbc, etc.) without having this problem.

Solution

  • If you use zeppelin 0.8, then you can set it in interpreter setting page.
