synchronized.Although ReentrantLock it is a very moving implementation, it has some important advantages relative to synchronized, but I think it is a serious mistake to rush to see synchronized as tossed. java.util.concurrent.lock the Lock class in is a tool for advanced users and advanced scenarios . In general, unless you Lock have

The most recent week is busy, the main work is to do a call "Keyboard Wizard" things, simply put a lot of data into memory, the data for quick retrieval, and then find the input conditions to match the best 10 records and show. Specific and the following two stocks of software related functions similar to: Data in the form of text exists in the file, and the volume of data is large, there are n

It would have taken more than 5 minutes to build, but now it has been shortened to 1 minute. However, after the overall version is upgraded to 2.0.0 one day, the manag

only need to write some packages that can achieve our goal, we will adjust it based on our specific needs ". However, it is often because you have quickly extended the compiled simple tool and tried to add more features until you compile a complete infrastructure service. At this point, you usually stick to the program you write, whether it is good or bad. You have already paid all the cost for building your own program, so in addition to the actual

Step 1: Test spark through spark Shell Step 1:Start the spark cluster. This is very detailed in the third part. After the spark cluster is started, webui is as follows: Step 2:Start spark shell: In this case, you can view the shell in the following Web console: Step 3:Copy the spark installation directory "readme. md" to the HDFS system. Start a new command terminal on the master node and go to the spar

Practice of setting a route table to restrict Website accessThe website that received this experiment: for short, "website", PING the website domain name and obtain the IP address. The IP address ends with. 69 www.2cto.com. Then, we can find out how many hops the route goes through under tracert.Www.2cto.com uses SolarWinds. Engineers to scan the IP address segment of the website. We know that there is

Step 4: build and test the spark development environment through spark ide Step 1: Import the package corresponding to spark-hadoop, select "file"> "project structure"> "Libraries", and select "+" to import the package corresponding to spark-hadoop: Click "OK" to confirm: Click "OK ": After idea is completed, we will find that the spark jar package is imported into our project: Step 2: Develop the first spark program. Open th

C ++ practice: implementation of a lightweight array class Note: This array class can be regarded as a simplified version of vector in the standard library: supports general operations on arrays, supports copying and assigning values, and supports redefinition of sizes. multithreading is not considered, no extra space is pre-allocated for performance optimization

Step 5: test the spark IDE development environment The following error message is displayed when we directly select sparkpi and run it: The prompt shows that the master machine running spark cannot be found. In this case, you need to configure the sparkpi execution environment: Select Edit configurations to go to the configuration page: In program arguments, enter "local ": This configuration indicates that our program runs in local mode
