运行一些 HBase 代码时出现以下问题。看起来它起源于 MXBean 位。我对此一无所知，但看起来相当低级。

看起来这已经在 HBase JIRA 上报告过了

https://issues.apache.org/jira/browse/HBASE-5718

他们认为这是一个 JMX 问题，我在查看下面的源代码后倾向于同意这一点。请注意关于从未见过原始数组的评论。不知何故，一个原始数组进入了这里，并被视为一个对象类。

  323       /* Make the converter for an array type, or a collection such as
  324        * List<String> or Set<Integer>.  We never see one-dimensional
  325        * primitive arrays (e.g. int[]) here because they use the identity
  326        * converter and are registered as such in the static initializer.
  327        */
  328       private static OpenConverter
  329           makeArrayOrCollectionConverter(Type collectionType, Type elementType)
  330               throws OpenDataException {
  331   
  332           final OpenConverter elementConverter = toConverter(elementType);
  333           final OpenType<?> elementOpenType = elementConverter.getOpenType();
  334           final ArrayType<?> openType = ArrayType.getArrayType(elementOpenType);
  335           final Class<?> elementOpenClass = elementConverter.getOpenClass();
  336   
  337           final Class<?> openArrayClass;
  338           final String openArrayClassName;
  339           if (elementOpenClass.isArray())
  340               openArrayClassName = "[" + elementOpenClass.getName();
  341           else
  342               openArrayClassName = "[L" + elementOpenClass.getName() + ";";
  343           try {
  344               openArrayClass = Class.forName(openArrayClassName);

验证您没有使用 OpenJDK 来运行 HBase。虽然从在线文档的先决条件列表中看不明显，但显然一些较旧的 Hbase 版本可能需要 Oracle Java。请参阅此链接。
