Java lang StringIndexOutOfBoundsException String index out of range

Hi,

I am getting an error in Spark. I tried to use groupByKey() function in scala. But it shows the below error.

ERROR executor.Executor: Exception in task 0.0 in stage 12.0 (TID 28)
java.lang.StringIndexOutOfBoundsException: String index out of range: 1

Can anyone tell me the reason?

Thank You

I also faced java.lang.stringindexoutofboundsexception: string index out of range: 0 problem. For my case I used map instead of flatMap. In flatMap each input item can be mapped to or more output items. So, you can try map in place of flatMap.

Thank You
