The group statement can put data with the same key valueAggregationTogether, there is an essential difference from group operations in SQL, where groups created by a group by sentence must be injected directly into one or more aggregate functions. There is no direct relationship between group and aggregate functions in pig Latin. The group keyword is as it is literally expressed:encapsulates all records containing the values corresponding to a particu

This question is the question of the combination of various number theory... The answer is ans = (G ^ sigma (C (n, d) % Mod. Then, by the ferma's theorem, ANS = (G ^ (SIGMA (C (n, d) % (mod-1) % mod Then, mod-1 is decomposed into 2*3*4679*35617, and Sigma (C (n, d) % m (m = 2, 3, 4679,356 17 Finally, we can combine the Chinese Remainder Theorem to quickly power the power! 1 /************************************************************** 2 Problem: 1951 3 User: rausen 4 Language: C+

Pig New System Test 3: iOS8.0.2 Originally, this cat had to wait for version 8.1 to come out and then perform the test again. Wait until the result is reached, that is, it was too late to push updates! What about iOS October 20 in 8.1? In an effort to write it up, I will not wait. Let's test the iOS 8.0.2 system! The 8. x System and the 7.1 system are still quite similar, only in some places are different. First, the screen display function is added t

Pig New System Test 4: Ubuntu 14.04, ubuntu14.04 At present, modemo generally uses the wubantu System in the office. On the one hand, the reason is that the old nature cannot run Windows. More importantly, the cat thinks that the Linux system is more open. besides, I am familiar with it now, and can be completely isolated from Windows! In this series of four new system testing articles, besides what iOS8 wrote on mac (it seems a bit too much to write

Physical plan generation process The optimized logical execution plan is logtophytranslationvisitor processed to generate a physical execution plan. This is a classic Vistor design pattern application scenario. Where the Logtophytranslationvisitor visit () is the entry method, through Dependencyorderwalker traversal handles each logicalrelationaloperator in the logical execution plan. Dependencyorderwalker traverses the nodes in the DAG in a dependent order, ensuring that it is accessed onl

Classical sorting algorithm-pig nest sorting pigeonhole sort The principle is similar to bucket sorting. It also requires a very large Pigeon nest. [This is called Bucket in bucket sorting. the name doesn't matter.] Pigeon nest is actually an array. The index position of the array indicates the value, and the value of the index position indicates the number of occurrences. If all the indexes are 1 or 0, the bucket is sorted. For example VaR pigeonhole
