The client calls the namenode to return a sorted list of datanodes for the first batch of blocks in the file. The client connects to the first datanode from the list. Detecting Wireless Hacker Program. The client streams the data block from the datanode. The client closes the connection to the datanode. The client repeats steps 3 5 for the next block or steps 2 5 for the next batch of blocks, or closes the file when copied. Read path 2T. White. Hadoop The Definitive GuideData read preferencesDetermines the closest datanode to the client. The distance is based on the theoretical network bandwidth and latency. Rack Topology feature has to be configured prior. Write pathA client creates a file by calling the create method on the Distributed. File. System object. The client calls the namenode to create the file with no blocks in the filesystem namespace. The client calls the namenode to return a list of datanodes to store replicas of a batch data blocks. The client connects to the first datanode from the list. The client streams the data block to the datanode. The datanode connects to the the second datanode from the list, streams the data block, and so on. The datanodes acknowledge the receiving of the data block. The client repeats steps 4 5 for the next blocks or steps 3 5 for the next batch of blocks, or closes the file when written. The client notifies the namenode that the file is written. Write path 2T.

IMPORTANT BRING YOUR OWN LAPTOP WITH WINDOWSTo get the most value out of the course, students are required to bring their own laptop so that they can connect directly to the workshop network. It is the students responsibility to make sure that the system is properly configured with all the drivers necessary to connect to an Ethernet network. Some of the course exercises are based on Windows, while others focus on Linux. VMware Workstation is required for the class. If you plan to use a Macintosh, please make sure you bring VMware Fusion, along with a Windows guest virtual machine. Windows. The course includes a VMware image file of a guest Linux system that is larger than 1. GB. Therefore, you need a file system with the ability to read and write files that are larger than 3 GB, such as NTFS on a Windows machine. IMPORTANT NOTE You will also be required to disable your anti virus tools temporarily for some exercises, so make sure you have the anti virus administrator permissions to do so. DO NOT plan on just killing your anti virus service or processes, because most anti virus tools still function even when their associated services and processes have been terminated. For many enterprise managed clients, disabling your anti virus tool may require a different password than the Administrator account password. Please bring that administrator password for your anti virus tool. We also require that no enterprise group policies be applied to the system. These policies can and will interfere with our labs. Enterprise VPN clients may interfere with the network configuration required to participate in the class. If your system has an enterprise VPN client installed, you may need to uninstall it for the exercises in class. VMware. You will use VMware to run Windows and Linux operating systems simultaneously when performing exercises in class. You must have VMware Workstation 1. You can download a free 3. VMware Workstation. VMware will send you a time limited license number for VMware Workstation if you register for the trial on their website. If you are using a Macbook or Macbook Pro with OS X 1. VMWare Fusion 5. 0 or later. Virtual. Box is not supported and may interfere with our labs. It should not be installed on a system you are planning to use for this class. We will give you a USB full of attack tools to experiment with during the class and to take home for later analysis. We will also provide a Linux image with all of our tools pre installed that runs within VMware Player or VMware Workstation. Linux. You do not need to bring a Linux system if you plan to use our Linux image in VMware. However, you are required to bring VMware Workstation. The class does not support Virtual. PC or other non VMware virtualization products. Mandatory Laptop Hardware Requirementsx. GHz CPU minimum USB Port. GB RAM or higher required 1. GB strongly recommended. Ethernet adapter a wired connection is required in class if your laptop supports only wireless, please make sure to bring a USB Ethernet adapter with youUSB Wireless adapter required. We recommend the following https hakshop. GB available hard drive space. Any Service Pack level is acceptable for Windows 1. Windows 8, Windows 7, or Windows Vista. As part of this class we will have wireless labs. If the machine you are using is a virtual machine, please bring an external USB wireless card. During the workshop, you will be connecting to one of the most hostile networks on Earth Your laptop might be attacked. Do not have any sensitive data stored on the system. SANS is not responsible for your system if someone in the class attacks it in the workshop. By bringing the right equipment and preparing in advance, you can maximize what you will see and learn as well as have a lot of fun. If you have additional questions about the laptop specifications, please contact laptopprepsans.
