在使用 hadoop中的 DistributedCache 把小份数据分布到各个计算节点时，每个 m

在使用 hadoop中的 DistributedCache 把小份数据分布到各个计算节点时，每个 maptask 执行任务的节点都需要加载该数据到内存，然后需要怎么做才能保证程序成功过运行？

Hadoop数据源及计算源支持二段式Principal

背景说明Principal（主体）是系统中的身份，如hadoop namenode等被赋予身份的人或事物。在Hadoop中，通常为集群中的每个服务和计算机创建不同的主体，例如hdfs/node1、hdfs/node2、...等等。这些主体将用于运行在node1、node2等上的所有HDFS守护程序。...

hadoop在MR计算时报错?报错

hdfs 已经格式化过了，启动后，执行一次pi值运算就报下面的错，运行别的任务也报类似错，请大神帮忙看看，先谢了 Error: org.apache.hadoop.mapreduce.task.reduce.Shuffle$ShuffleError: error in shuffle in ...

基于Hadoop分布式集群搭建政企大数据计算存储服务平台_数道云科技

今天，小编就据目前互联网行业的发展，以及大数据Hadoop分布式集群等等来讲解一下，政企如何搭建大数据计算服务平台。互联网信息技术的迅猛发展，云计算、物联网、智能科技、AI、超级计算机等等的出现和发展，使数据量不断增长，可以说是呈现“巨量”增长的趋势，由此产生的庞大数据量已经不能用传统的数据统计来计...
