My jar in localhost or at AWS EC2 instance works like a charm, but just on Elastic MapReduce it fails with a "Never seen" Exception:
Caused by: java.lang.IllegalArgumentException: class=class com.alvazan.orm.impl.meta.data.MetaClassSingle has two fields that have @NoSqlId annotation. One of them may be in a superclass
I have tried to remove the (usegenerator = true) from @NoSqlId, but didn't work.

We have seen this issue ourselves recently and put a temporary fix in. Grab the latest from master branch and try that and let me know. The new code looks like this so it should tell us the two fields (or not scan that field twice).
if(metaClass.getIdField() != null) {
Field existingField = metaClass.getIdField().getField();
if(field.equals(existingField))
return true; // we already processed it
else
throw new IllegalArgumentException("class="+metaClass.getClass()+" has two fields that have @NoSqlId annotation. One of them may be in a superclass. The two fields are="+field+" and="+existingField);
}
NOTE: We are also looking for a better fix as sometimes this is caused by a double scan of a class file so we probably have another fix coming by the end of this week....we are currently talking about it via email right now.
Also, this issue is caused by scanning a class twice....is any of your code calling rescan method in NoSqlEntityManagerFactory? (I am thinking not). The latest should solve your issue for now and check back next week too.
