香港服务器103.14如何处理故障源
自动保存数据的多个副本，144.18并且能够自动将失败的任务重新分配。Hadoop带有用Java语言编写的框架，103.14因此运行在Linux生产平台上是非常理想的。Hadoop上的应用程序也可以使用其他语言编写。

一个处理大数据的软件框架，虽然受到众多商业公司的青睐，但是其自身的技术特点也决定了它不能完全解决大数据问题。在当前Hadoop的设计中，所有的metadata操作都要通过集中式的NameNode来进行，NameNode有可能是性能的瓶颈。
当前Hadoop单一NameNode、单一Jobtracker的设计严重制约了整个Hadoop可扩展性和可靠性。首先，NameNode和JobTracker是整个系统中明显的单点故障源。再次，单一NameNode的内存容量有限，使得Hadoop集群的节点数量被限制到2000个左右，能支持的文件系统大小被限制在10-50PB，最多能支持的文件数量大约为1.5亿左右。
