I connect to spark using this code:
sc <- spark_connect(master = "local")
Got some error messages:

I figured out that this may be some problem with spark configuration, but don't know how to deal with this issue. Is it related to Java?
It is because of the Java version. A lower Java version would work. Please see the link for my solution.
