Converting a column from a schemaRDD to a string array

I may not understand correctly what you are looking for, but I'll try. You need to read a line of String and split the String into array by spaces

val converted =>
{line(7).split(" ")})

The problem here is that (depends what you are doing) "Exception in task 1.0 in stage 2.0 (TID 5)" should be as a one String, not splitted. To do this we need:

  • split string as " " to array
  • create array from first 4 columns
  • add to this array merged string from the right subarray


val columns = line(7).split(" ")
columns.take(4) :+ columns.drop(4).mkString(" ")

Converting Javascript Array to PHP Array
You can do this in many ways, two of the "best" would be 1, sending variables in the format variable[key] = value php will reconise this and do the the conversion so $_GET['variable']['key'] would contain value. 2, send it as a JSON string use JSON.stringify(yourArray); (NOTE: IE8 and above support this, older versions need a libary like j

Check if array of string A has letters that exist in array of string B (Not working)
This works for me (I think you dont want to compare the last char ()?) , as rusol said, comparing every char of the UserInput. It prints the position of the characters that are equal in both arrays: void doLettersMatch(char userInput[], char letters[]) { int i; for (i = 0; i<6; i++) { if (userInput[i] == letters[i]){ printf("The character %c exists in both strin

converting InetAddress to string
This is a small program, to check what you want. Same piece of code, what you have shared, it is working fine. public static void main(String args[]) { Hashtable<String, InetAddress> fileLocation = new Hashtable<String, InetAddress>(); InetAddress addr; try { addr = InetAddress.getByName(""); fileLocation.put("ABD_9158", addr);
