开源大数据平台 E-MapReduce spark-阿里云

T-thinker | 继MapReduce, Apache Spark之后的下一代大数据并行编程框架

[欢迎随时跳过文字看最后的讲座视频直接了解 T-thinker]。什么？是不是又是一个关于设计大同小异的并行编程框架的炒作？是不是又是把各种简单烂大街问题（join, connected components, single-source shortest paths, PageRanks）统一一下...

HADOOP MapReduce 处理 Spark 抽取的 Hive 数据【解决方案一】

开端：今天咱先说问题，经过几天测试题的练习，我们有从某题库中找到了新题型，并且成功把我们干趴下，昨天今天就干了一件事，站起来。沙问题？java mapeduce 清洗 hive 中的数据，清晰之后将driver代码进行截图提交。坑号1: spark之前抽取的数据是.parquet格.....

Spark将Hadoop（主要是指MapReduce）的性能提升了一个量级，主要的得益于那两个方面？

Spark完全可以取代mapreduce吗？

Spark完全可以取代mapreduce吗？为什么？什么场景下可以取代？什么场景下不能取代？

Mapreduce操作的mapper和reducer阶段相当于spark中的什么算子？

spark资源粒度比MapReduce快的原因是什么？
