             Summary: Sqoop2: RESTiliency: Remove repetitive try-catch block for accessing POST and PUT request
                 Key: SQOOP-2823
                 URL: https://issues.apache.org/jira/browse/SQOOP-2823
             Project: Sqoop
          Issue Type: Bug
            Reporter: Jarek Jarcec Cecho
            Assignee: Jarek Jarcec Cecho
             Fix For: 1.99.7
         Attachments: SQOOP-2823.patch

I've noticed that we have quite a few repetition of code like this one:

{code}
     RoleBean bean = new RoleBean();

    try {
      JSONObject json = JSONUtils.parse(ctx.getRequest().getReader());
      bean.restore(json);
    } catch (IOException e) {
      throw new SqoopException(ServerError.SERVER_0003, "Can't read request content", e);
    }
{code}

It's relatively a lot of code just because {{ctx.getRequest()}} can throw an exception. I would like to propose to create a method in our {{ctx}} wrapper to provide the {{getReader}} method without any exception, which will simplify the code to:

{code}
    bean.restore(JSONUtils.parse(ctx.getReader()));
{code}

We'll of course throw an exception on failure - but using our {{SqoopException}} mechanism.
