Summary: The advent of Apache Spark has made it possible for ordinary people to have big data and real-time data analysis capabilities. In view of this, this article through hands-on Operation demonstration to lead everyone to learn spark quickly. This article is the first part of a four-part tutorial on the

If you use-p or-p, the container will open some ports to the host, as long as the other side can connect to the host, you can connect to the inside of the container. When using-P, Docker will randomly find an unoccupied port between 49153 and 65535 in the host to bind to the container. You can use Docker port to find this random bound port.
If you append-d=true or-D
The spark kernel is developed by the Scala language, so it is natural to develop spark applications using Scala. If you are unfamiliar with the Scala language, you can read Web tutorials A Scala Tutorial for Java programmers or related Scala books to learn.

For any JVM process, you can use-XMX and-XMS to configure its heap size (heap sizes). The question is: how do these processes use its heap memory and why do you need it?

Although the first approach reduces HTTP requests, merging different types of code into a single file violates the principle of division of labor. The second method is just ahead of the download time and does not reduce the HTTP request.Third, the concept of server pushServer push refers to the server pushing various resources to the browser without

These are all master. Other services, such as the WEB application proxy server and the MapReduce Job history server, run on a
