Hadoop安全性问题

Hadoop作为一种分布式计算框架，在处理大数据时提供了诸多优势，但同时也面临一些安全性问题。以下是Hadoop面临的一些主要安全性问题：缺乏安全认证机制：Hadoop在基本的用户名和密码措施之外，缺乏完善的用户认证管理机制。这可能导致恶意用户轻易伪装成其他用户，窜改权限或进行非法访问。例如，未经授权的用户可能能够提交作业、修改JobTracker状态、修改HDFS上的数据，甚至伪装成D...

Apache Hadoop的核心原则就是转移计算比转移数据代价更低。这就是我们尽可能地将计算转移到存储数据之处的原因。因此，HDFS通常使用大量的本地读取，也就是说，读取数据的客户端和要读取的数据在同一节点。起初，HDFS本地读取和远程读取使用同一种方式：客户端端通过TCP套接字连接DataNode，并通过DataTransferProtocol传输数据。这种方式很简单，但是有一些不好的地方。例....
