-------------------------------------

Thanks for pointing this out. Looks like the timeout was previously set to 6000.

> 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]
