I got zero marks in the first assignment because Yifang Sun did not mention Spark is running on parallel. That means a code that seems correct on a single thread (which is the COMP9021 style), could have a different result on Spark. This lecturer is terrible and irresponsible I would like to say since a lot of the contents taught by him were wrong. Worse still, in the final exam, he asked students the issue in assignment 1 which led to almost 50 students got zero marks, though the associated answer had not been taught in the lecture at all!! Be careful of this lecturer!!

Lecter: Yifang Sun,今年是他第一年教书,明显感觉授课技巧不足,英文表达能力较弱。但也因为这个,他对知识点阐述是非常详细的,只不过几乎每周课程都会说错一点或者课件写错一点,两三句能讲明白的东西他要讲很多例子才能明白他的意思。


Lecture:上课方式是提前将录好的课程放在Google Drive和百度网盘上,让学生自己去下载观看。挺贴心的,对因为疫情在国内来不了的同学来说,避免了网络链接不方便的问题。课程内容,我个人挺喜欢的,因为有很多数学计算的部分我很喜欢


2Project+1Assignment+3Lab:lab不算分而且第一个lab是搭建环境,Project1的分数设置出现了大问题,只要代码没有run对结果就给0分,无步骤分,而且运行效率也影响评分。所以很多同学为了追求效率,不断完善修改自己的代码,修改到最后,之前对的地方给改错了,导致0分。第二个project和assignment明显就改进了,拆成了很多小步骤。

感觉这门课教的Hadoop和Spark都太浅了....

课程质量低劣,前半部分上课的内容就是Hadoop的hello world,spark的hello world。后半部分的理论部分也不够详细,不够深入。

9313不得不说是一门好课,讲的是Hadoop和Spark,老师和tutor都很好。曹老师内容讲的也很扎实,每一周都有相应的lab去练习,真的很不错,作业设置也很合理,总而言之这门课挑不出任何毛病。但是如果没有JAVA基础的话一定要慎选,慎选,慎选。后面还会用到Scala,很有意思
