Text/figure dfPE file, the full name of Portable Executable file, is a common format for Windows system Executable files, such as EXE, DLL, OCX, and even SYS files that we usually contact belong to the scope of PE files. To easily reference other types of resources in an executable file, the PE file has an independent resource segment that links all the resource files required for program execution to the

Use Cases of hive concurrency Model Concurrency support (http://issues.apache.org/jira/browse/HIVE-1293) is a must for databases and Their Use Cases are well understood. At least, we should try to support concurrent reading and writing. It is useful to add several locks that are currently locked. There is no direct requirement to add an API to explicitly obtain the lock. Therefore, all locks are obtained i

default database table is stored in the/user/hive/warehouse directory.(1) TextfileTextfile is the default format and is stored as a row store. Data is not compressed, disk overhead is large, data parsing cost is large.(2) SequencefileSequencefile is a binary file support provided by the Hadoop API, which is easy to use, can be segmented, and compressible. Sequencefile supports three types of compression options: NONE, RECORD, BLOCK. The record compre

Windows PE is a computer's smallest operating system for Windows installation preparation. May still not quite understand, so to speak, we can when the computer does not install the system Windows operating environment called PE. PE refers to the Windows Preinstallation Environment, a minimal WIN32 subsystem with limited service, based on the Windows XP Professio

The new weather for the new semester is generally the beginning of the primary school composition. Recently, I have had time to take a closer look at the structure of the PE file. In the past, when I encountered such a problem, I always split the east wall to make up the west wall. I have not learned well enough. After several days of research, I will share with you. The file structure of PE starts from the

When a PE file is executed, the PE loader first checks the offset of the PE header in the DOS MZ header. If found, jumps directly to the location of the PE header.When the PE loader jumps to the PE header, the second step is to ch

Hive Command Line interface The command-line interface, the CLI, is the most common way to interact with hive. Using the CLI, users can create tables, check patterns, query tables, and so on.

Technical Foundation: Write Shell programs, understand the PE Structure, and X86 command systems.Development tools: MASM, VC ++ 1. We sometimes make a lot of changes to some of the calls when transforming a PE.Wait, often add a section manually, complete the call transformation in this section, and then return to the original place to continue the execution. Although this method is feasible, the workload is too large and debugging is very inconvenient
