Hi Kevin,
I tried the latest master branch ("522e66d9ea04502b4a98bb28642fb4724ff0a479")
in R 3.5.1, but the `checkUserInterrupt` still does not throw the exception.
The R is under a docker container (library/r-base:3.5.1), so there should
be no GUI.
Hope these info helps.

Is there a way to query the cassandra based on the key in rdd1?
Here is some information of our system:

Dear all,
I am a new spark user from R.

It seems that raising R error causes the memory error, is it?

By the way, maybe you should look two files in `inst`.
The `gen_function.R` crawls http://redis.io/commands and generates the
command according to the official redis manual. You could modify
`template.R` to generate the helper functions dynamically based on the
exposed Rcpp function.
Hope it help
