java lang StringIndexOutOfBoundsException String index out of range 1

Question

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
 

Answer 1

Hi@akhtar,

I also faced this same 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

When using the Java substring() method, a subset of the character sequence can be extracted from a string. The substring index must be any value from 0 to the length of a string. The java.lang.StringIndexOutOfBoundsException thrown by String methods to indicate that the beginIndex is negative , or endIndex is larger than the length of this String object, or beginIndex is larger than endIndex. 

How to solve the StringIndexOutOfBoundsException

• Check the length of the string before using substring()
• Exception handling using try...catch.
