最近别人给了朋友两只guinea pigs, 非常的可爱，可能是因为刚换了环境，跟朋友一
家还不是很亲，但是朋友的小孩很喜欢。但是矛盾来了，朋友的婆婆说不让养，说有味
道对孩子呼吸道不好，影响孩子成长，还为这个闹过一次。有一次小朋友可能是去喂它
们不小心被咬到了，小动物没有看到以为小手就是吃的，据说就是挂了下，小朋友就小
哭了一下，结果奶奶就过去对着guinea pig笼子一顿打，还说什么让你咬人，我就不让
你活
，弄死你，药死你之类的话。朋友听了心惊胆颤，但是也不好说什么。现在朋友左右为
难，本来是想让小动物跟小朋友一起成长，让小朋友有责任感，但是因为这个引起家庭
矛盾又确实不值得，尤其还是跟孩子奶奶。请问这样的情况该怎么办呢 |

发帖数: 6348 | 7 Hi all,
Just wondering if any of you had the same problem and if you know the cause.
I have a dataset of site-visitor pairs, which records daily visits to
websites.
While filtering the data using domain "espn.com", there are 306 unique
visitors; while joining the data with the list of domain names, I only got
176 unique visitors to "espn.com".
This is weird since conceptually both filtering and joining use hash tables
the same way.
PS: pig didn't drop bags during the join, at least it didn't tel... 阅读全帖 |

works without mapreduce runs..
check the table for pig SUM :
http://pig.apache.org/docs/r0.7.0/piglatin_ref2.html#SUM:
SUM returns long when input is int, but you assign it to cost: int..
This is where the runtime error comes from, I believe. change to "cost: long
", or simply "cost" without type specification..

发帖数: 4107 | 16 最近在自学, 请问, pig能做iterative的问题吗, 比如一些matrix update的问题的.
比如nonnegative matrix factorization, 有一个nonnegative matrix N, 要分解成2
个matrix A和B, 使得|N-A*B|尽可能的小
标准算法是: 先随机生成2个矩阵A和B. 然后先固定A, 按照一个规则用A和N去更新B;
再固定B, 用B和N去更新A; 一直如此循环更新, 直到|N-A*B|足够小
不知道用pig或者hive, 能解决如此问题吗?
(不是research问题, 5/6年就有人用mapreduce+java发了N片文章)
当然, 我是说不另外写UDFs的情形下 |

发帖数: 119 | 17 我看是不能的。Pig Latin是一种 data flow language，定义的是数据处理流，而不包
括如何控制数据的处理。后者需要编程语言，比如python或者java。这两种语言都可以
很好的和Pig接口。 |

疯狂的越南生猪走私：一天1.5万头偷渡中国
据央视新闻客户端11月20日消息，中国和越南的边境上素有“互市”的传统，但从越南
进口生猪是不允许的，因为口蹄疫原因，从2003年开始，农业部就禁止从越南进口生猪
。然而记者前不久在广西崇左市宁明县爱店镇调查时发现，这里每天有约1.5万头越南
生猪通过各种“走私通道”进入中国，流入内地一些屠宰场。
央视记者经过数月跟踪调查，揭开了这条越南生猪走私的非法利益链。
