Description

JsonToBean has code to map from Bundle Job, Coordinator Job, etc JSON into the associated BundleJob, CoordinatorJob, etc classes.

If a mapping is missing, and you try to call a getter, the code will compile but you'll get a RuntimeException. For example; the mapping for BundleJob.getAcl() is missing. Specifically, when you use this code:

BundleJob job = client.getBundleJobInfo(jobId);
String acl = job.getAcl();

you get this exception:

Exception in thread "main" java.lang.RuntimeException: Undefined method mapping: getAcl
	at org.apache.oozie.client.rest.JsonToBean$JsonInvocationHandler.invoke(JsonToBean.java:217)
	at com.sun.proxy.$Proxy4.getAcl(Unknown Source)
        ...

There are a few inconsistencies including extra mappings, missing mappings, and missing information from the server.

We should:

1. Fix these inconsistencies.
2. Write tests to prevent this sort of thing from happening in the future.
