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 = jsonFiles.map(line=>
{line(7).split(" ")})
converted.collect

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

code:

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

Converting a string into a JSON obj or array JavaScript

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. http://php.net/manual/en/language.variables.external.php 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("127.0.0.1"); fileLocation.put("ABD_9158", addr);
