偏底层未必简单，比如做网站的话，infra比搞crud的app难
但是具体到big data这一块，big data的infra的确比app简单
具体点说就是hadoop的确比spark简单
hadoop尤其是hdfs其实就是一个简单的统一封装的file system
就是拷贝google的gfs，阿三，尤其是在狗的阿三，平常就在维护gfs
学会了之后就出来把gfs用java实现一遍，就可以拿出去忽悠了
多好？多简单，尤其是java又屏蔽了不少底层的细节
有这个容易赚的钱先赚了再说
相比之下，big data的app上来就要涉及各种高等数学
线性代数，统计这些，比起来，当然还是file system容易搞了 |

发帖数: 710 | 5 这两天收到打车app，租房app，某all in one hr平台的口头offer，package细节下周
能出来，这周末提前好好考虑下。
另外手里还有个fb的offer保底。
板上大牛们帮分析下，现在去哪家还能有点汤喝？
---
10/28 update
准备卖身去打车公司当司机了，要去的组我非常喜欢，感觉能学到很多东西。
其实租房网也很不错，我其实纠结了很久。他们家去了之后基本可以随便去喜欢的组，
做喜欢的事情，这点很给力。至于车间的装修多么的好，我就不用说了，大家随便搜搜
图片就可以看出来。
但是综合来看，最后还是选择去当司机。主要是以下几点原因：
1. 要去的组业务多，公司貌似很重视。我觉得很能锻炼人，这个对new grads来说比什
么都重要。
2. 要去的组同胞多，甚至基本都是同胞。我觉得在美国，真正最后能帮上忙称之为人
脉的，永远只能是同胞。
3. 未来的manager是标准的德艺双馨，我打听了很多人，都说口碑很好。我觉得找工作
跟找phd有些许相似的地方，公司本身未必那么的重要，去哪个组以及你的老板怎么样
，有时候能直接决定你的career path。

there are a lot of commonality between these big data technologies...

发帖数: 7881 | 8 小姐啊， mapreduce的input哪里来？
是hdfs file么？ 一般来说， keyvalue是一个个进到你的system里来。 比如你的
sytem前面有个webservice， 然后client可以call你的service， 给你keyvalue， 你
直接写到HDFSfile里？ 一般都是写到database里， 然后高兴怎么算就怎么算。
HBase的rowcount本来就是个mapreduce function

|
z****e
发帖数: 54598 | 10
hdfs无所谓什么pair
直接丢一个file进去都行
只有search时候需要用sstable，因为需要建inverted index table
hashset底层实现就是一个hashmap
set更为傻瓜一点，因为帮忙干掉了duplicate
一般对于这种去重的需求，都用set
所以阿三提示得很好啊
然后follow up错得太离谱
persistence也有hashcode的用武之地
逻辑上是一样的 |

首先， 你他妈的干嘛要存在HDFS里？ 要存， 也要存在Hbase、cassandra里啊。。。
然后你这input data {logitutde， lagitude， driverID} 拿到以后， 怎么算某个区
域有多少出租车啊？ 主要讲这个吧。。。 |

HBase和Cassendra不也是存在HDFS上么。 ：）

故事背景：手上有一些offer，现在除了google（SDE3），hulu其他都给拒了。G的
deadline在周四。
本周一刚onsite了Pinterest（运气好，求别问如何拿到面试）。跟HR说了deadline就
在周四，对方也同意周三给结果。
但是，已经差不多过了周三，还是没信儿（我还发了邮件催，得到的只是ASAP）。
问了内推哥们，说feedback好像没有非常好。
说说我自己的感觉：自认为面的没啥问题，算法题不难都做出来了，设计题也扯了一堆
画了一堆（之前给hdfs，hive贡献过，自认为还比较能扯）。以往面试经验也够多，除
了palantir挂了，其他都是positive。自信心也强，所以听到feedback没有非常好后还
挺纳闷的。
想请问，这种情况是凶多吉少还是怎么的？有啥好策略不？新人求带。
感谢老司机 |
