Class InstantiationIOException

java.lang.Object

java.lang.Throwable

java.lang.Exception

java.io.IOException

org.apache.hadoop.fs.PathIOException

org.apache.hadoop.fs.s3a.impl.InstantiationIOException

All Implemented Interfaces:

Serializable

public class InstantiationIOException
extends org.apache.hadoop.fs.PathIOException

An instantiation exception raised during reflection-based creation of classes. Uses an enum of kind so tests/code can examine it, without creating a full hierarchy of exception classes.
