August 2014 HUG : Hive 13 Security
The document discusses security concepts and authorization solutions for Apache Hive. It introduces key security concepts like authentication and authorization. It then describes different authorization solutions for Hive including storage-based authorization using HDFS permissions, SQL standard-based authorization using grant/revoke statements in HiveServer2, and extending Hive authorization using plugins. It concludes by discussing use cases implemented at Yahoo, including row and column level access controls using HiveServer2 and views, and limited authorization for the Hive CLI.
Apache hive
Apache Hive is a data warehouse software that allows querying and managing large datasets stored in Hadoop's HDFS. It provides tools for easy extract, transform, and load of data. Hive supports a SQL-like language called HiveQL and big data analytics using MapReduce. Data in Hive is organized into databases, tables, partitions, and buckets. Hive supports various data types, operators, and functions for data analysis. Some advantages of Hive include its ability to handle large datasets using Hadoop's reliability and performance. However, Hive does not support all SQL features and transactions.
Apache Hive
Hive is a data warehouse system for Hadoop that facilitates easy data summarization, ad-hoc queries, and the analysis of large datasets stored in Hadoop compatible file systems. Hive provides a mechanism to project structure onto this data and query the data using a SQL-like language called HiveQL. At the same time this language also allows traditional map/reduce programmers to plug in their custom mappers and reducers when it is inconvenient or inefficient to express this logic in HiveQL.
Introduction to HiveQL
Interested in learning Hadoop, but you’re overwhelmed by the number of components in the Hadoop ecosystem? You’d like to get some hands on experience with Hadoop but you don’t know Linux or Java? This session will focus on giving a high level explanation of Hive and HiveQL and how you can use them to get started with Hadoop without knowing Linux or Java.
Tabla periodica y sus propiedades periodicas
El documento resume las propiedades periódicas de los elementos químicos, incluyendo cómo varían el tamaño atómico, la energía de ionización, la afinidad electrónica, la electronegatividad y la reactividad a través de la tabla periódica. Explica que estas propiedades tienden a aumentar al descender en un grupo y disminuir al avanzar en un período, con algunas excepciones. También clasifica los elementos como metales, no metales y semimetales según su facilidad para ganar o perder
Energia hidraulica 1
El documento describe la energía hidráulica, incluyendo su origen en la energía solar, su historia de aprovechamiento por los egipcios, romanos y en la Edad Media, y cómo actualmente se usa principalmente para generar energía eléctrica en centrales hidroeléctricas que pueden ser de agua fluyente o de pie de presa. Explica también el proceso de conversión de la energía potencial y cinética del agua en energía eléctrica a través del uso de turbinas.
Apache Hive - Introduction
This document provides an introduction to Apache Hive, including:
- What Apache Hive is and its key features like SQL support and rich data types
- An overview of Hive's architecture and how it works within the Hadoop ecosystem
- Where Hive is useful, such as for log processing, and not useful, like for online transactions
- Examples of companies that use Hive
- An introduction to the Hive Query Language (HQL) with examples of creating tables, loading data, queries, and more.
Hadoop hive presentation
Hadoop is an open-source framework for distributed storage and processing of large datasets across clusters of commodity hardware. It addresses problems with traditional systems like data growth, network/server failures, and high costs by allowing data to be stored in a distributed manner and processed in parallel. Hadoop has two main components - the Hadoop Distributed File System (HDFS) which provides high-throughput access to application data across servers, and the MapReduce programming model which processes large amounts of data in parallel by splitting work into map and reduce tasks.
Well logging and interpretation techniques asin b000bhl7ou
This document provides an introduction to sedimentary rock properties for well log interpretation. It discusses how sedimentary rocks form from the weathering and alteration of existing rocks. Sedimentary rocks are composed mainly of minerals stable under normal surface conditions and may be classified as mechanically or chemically derived. Mechanical rocks include sandstones and conglomerates, while chemical rocks include carbonates and evaporites. Well logs are useful for characterizing sedimentary rocks and pore fluids in order to understand petroleum reservoirs.
