127 is a parsing error that usually comes from R, it’s perfectly not a workspace issue. If you want to get a specific error message. Join a call that can run your script / r command with the following switches to get an error response. I’ve used it in every one of our past years and it works well.
I created data in 5 hours. I want to help you predict dates from the fifth hour to four hours of comprehension (memory is associated with the date).Using hourly data, I create a new collection and add the predicted data for the last hour to the new collection. But I get a specific error:
The following exception is broken on eval, request status: Error code: 127org.rosuda.REngine.Rserve.RserveException: validation failed, request status: error code: 127at org.rosuda.REngine.Rserve.RConnection.eval (RConnection.java:233)in scheduler.scheduler.predictions.getPredictionsofData (predictions.java:45)at pack.GetCollectionMultithreaded.getPredictionAndInsert (GetCollectionMultithreaded.java:386)at pack.GetCollectionMultithreaded.runCustomerListAndPredictionEvery5Min (GetCollectionMultithreaded.java:155)at pack.GetCollectionMultithreaded.main (GetCollectionMultithreaded.java:103)

I useI use Spark 2.0., 2 when I run a function with R commands for over 2 million observations (string). it takes 3 hours to complete, plus one function.
callfunction <- successful declarations (dataframe) return (final_dataframe)}
my_function <- data.frame (callfunction (dataframe))str (my_function)
The result of str () intent is displayed on the patch. but when I want to call new commands in the next cell the error shows the following:
