If i feed html files in the form of Array[Byte] at producer side in kafka then how to reconstruct html file at consumer side in kafka ?

This is how i am converting html files into Array[Byte]

def getByteArray(fileName: String): Array[Byte] =
 {
   val file: File = new File(fileName)
   val fileinputstream: FileInputStream = new FileInputStream(file)
   IOUtils.toByteArray(fileinputstream)
 }

suggest me solution which will give the file back at consumer side by applying that function. e.g.

def byteArrayToFile(data:Array[Byte]):String={
//suggest
}

Do the opposite of what you did on the client to get to the byte array format? This doesn't sound like it's specific to kafka. – 500 - Internal Server Error Oct 03 '19 at 12:21

`new String(data, "UTF-8")`?? – OneCricketeer Oct 05 '19 at 18:23

What you show looks like `data.toString`... There's only so many ways to get bytes to a String, and that's not it – OneCricketeer Oct 07 '19 at 08:56
