经过两天的折腾,一个对c++和机器学习库的安装都一知半解的人终于在反复安装中,成功的将shark库安装好了,小小纪念一下,多亏了卡门的热心帮忙. shark的安装主要分为以下几个部分: (1)下载 shark,cmake,和boost 从这个网页里面可以找到这三项的下载地方http://image.diku.dk/shark/sphinx_pages/build/html/rest_sources/getting_started/installation.html 同时,这个也是shark安装指…

题 Today, Wet Shark is given n integers. Using any of these integers no more than once, Wet Shark wants to get maximum possible even (divisible by 2) sum. Please, calculate this value for Wet Shark. Note, that if Wet Shark uses no integers from the n …

题 There are n sharks who grow flowers for Wet Shark. They are all sitting around the table, such that sharks i andi + 1 are neighbours for all i from 1 to n - 1. Sharks n and 1 are neighbours too. Each shark will grow some number of flowers si. For i…

Shark是构建在Spark和Hive基础之上的数据仓库. 目前,Shark已经完成学术使命,终止开发,但其架构和原理仍具有借鉴意义. 它提供了能够查询Hive中所存储数据的一套SQL接口,兼容现有的Hive QL语法. 这样,熟悉Hive QL或者SQL的用户可以基于Shark进行快速的Ad-Hoc. Reporting等类型的SQL查询. Shark底层复用Hive的解析器. 优化器以及元数据存储和序列化接口. Shark会将Hive QL编译转化为一组Spark任务,进行分布式运算.…
