package com.netflix.hystrix.exception;

import com.netflix.hystrix.HystrixCommand;


An exception representing an error with provided arguments or state rather than an execution failure.

 Unlike all other exceptions thrown by a HystrixCommand this will not trigger fallback, not count against failure metrics and thus not trigger the circuit breaker. 

NOTE: This should only be used when an error is due to user input such as IllegalArgumentException otherwise it defeats the purpose of fault-tolerance and fallback behavior.
