ローカルホストまたは AWS EC2 インスタンスの私の jar は魅力のように機能しますが、Elastic MapReduce だけでは「見たことがない」例外で失敗します:
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
@NoSqlIdから(usegenerator = true)を削除しようとしましたが、うまくいきませんでした。
