inconsistent-error-format

[Dmitriy Ukhlov]

Error details returned from REST API as part of http response body have
more than one format.
FORMAT 1:
----------
{
explanation: "The resource could not be found."
code: 404
-error:
{ message: "Table 'resources111' does not exist" traceback: null type: "TableNotExistsException" }
title: "Not Found"
}
In some cases we also get error response in following format
FORMAT 2
----------
{"__type":"com.amazonaws.dynamodb.v20111205#ResourceInUseException","message":"T he resource which you are attempting to change is in use."}
It would be good to have all errors returned in same consistent format.

    Fix error handling

    In some cases our code throws Amazon DynamoDB specific
    exceptions even we work with REST API.
