             Summary: SparkR interpeter does not connect to Spark 2.1
                 Key: TOREE-396
                 URL: https://issues.apache.org/jira/browse/TOREE-396
             Project: TOREE
          Issue Type: Bug
            Reporter: Mario Briggs


I was trying the SparkR interpreter and trying to connect to a Spark 2.1 cluster. I get the following failure when execute any cell

"Failed to connect JVM: Error in socketConnection(host = hostname, port = port, server = FALSE, : argument "timeout" is missing, with no default
Calls: sparkR.connect ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
"
Looks like in Spark2.1, the [timeout|https://github.com/apache/spark/blob/branch-2.1/R/pkg/R/client.R#L22] param to sparkRConnect no longer has a default value. 
So this needs to fixed in [here|https://github.com/apache/incubator-toree/blob/master/sparkr-interpreter/src/main/resources/kernelR/sparkr_runner.R#L65]
