i have a spark stream code that read from kafka, but the value that i have is like this:

```
"{ id:'1',name: 'John', address: 'Highway 37' }|{ id:'2',name: 'Marta', address: 'Highway 37' }|{ id:'3',name: 'Juan', address: 'Highway 37' }|{ id:'4',name: 'Erick', address: 'Highway 37' }|{ id:'6',name: 'Alex', address: 'Highway 37' }|{ id:'7',name: 'Juanjo', address: 'Highway 37' }|{ id:'8',name: 'Pam', address: 'Highway 37' }|{ id:'9',name: 'Paty', address: 'Highway 37' }|{ id:'10',name: 'Diana', address: 'Highway 37' }"

```

is a string set of json, this is my kafka value:

```
val kafkaRawData = df.selectExpr("CAST(value AS string)")

```

but i want to convert this string json set of data to dataframe or dataset, and how could i do it???
