cannot communicate with client version 4Error. This is the hint version of the wrong, I see. The remote Hadoop version is different from the jar package version. Remote is 2.7.2. So I changed the Hadoop jar package to that version (2.* version should be able to, if not similar can be used)And then I changed the wrong one.The data was found to be due to the fact that Windows local Hadoop was not winutils.exe. The mechanism of native Hadoop is going to call this program. We're going to download t

Undefined reference to ' pthread_create ' Undefined reference to ' Pthread_join ' Problem Reason: The Pthread library is not the default library of the Linux system, which requires the use of a static library libpthread.a, so that when you create a thread using Pthread_create () and call the Pthread_atfork () function to establish a fork handler, You need to link to the library. Problem

and programming level is extremely limited, and then change the change is not moving ... Also hope to have a master generous enlighten, in the next first thanked!This test through the classmate raised a problem, verify the importance of algorithm and programming optimization, just use a most simple low-level optimization, then the calculation efficiency increase

for the left-to-right (I! = 1 and I! = N), you can get the formula:G (i) = f (i-1) + f (n-i)To verify authenticity, verify by n=3.N=3F (1) = 1;F (2) = 3;F (3) = f (1) + F (2) + 1 = 5There are two boundaries and an intermediate point, and the middle point evaluates toG (2) = f (1) + f (1) = 2Then the final result is 2 + 5 * 2 = 12Then 12 times 2 of three squares: 12 * 8 = 96Problem solving.The implementation code is as follows:#include #define MOD (i) (i)% 1000000007Long Longborder[1010] = {0};i

Have done the third batch of topics, today headline 2018 Campus recruitment back-end development engineer (third batch) programming questions-the problem. The topic of this field is biased by techniques and algorithms, while the third instalment of the problem-biased coding. The algorithm involved has two-part search and interval dynamic

This paper illustrates the knapsack problem solving method of C + + dynamic programming. Share to everyone for your reference. The specific analysis is as follows: Problem Description: The maximum capacity of the backpack is w, there are n items, each item weight of W, value for p, how to select items can make the go

Began reading "Programming Zhu Ji Nanxiong", just read the opening to feel very happy. The author starts with "A friendly conversation", probably like this: A programmer asked the author: "How does I sort a disk file?" The author briefly describes how to implement merge Sort on disk and suggests that he delve into algorithmic textbooks first. However, programmer is concerned with how to solve the problem ra
