'Cannot connect to Spark through sparklyr in RStudio

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?

sparklyr


Solution 1:[1]

It is because of the Java version. A lower Java version would work. Please see the link for my solution.
