Benchmarks have been observed to be notorious about biasing due to minor software tricks and hardware settings. Apache Pig applies the fundamentals of familiar scripting languages to the Hadoop cluster. Impala uses Hive megastore and can query the Hive tables directly. This three-day instructor-led training addresses traditional data analysis techniques, analytics with SQL, and other scripting languages. Both Apache Hive and Impala, used for running queries on HDFS. Impala uses a SQL-like syntax to interact with data, so you can leverage the existing BI tools to interact with data stored on Hadoop. The tpcds__parquet table definition and information can be seen here in Hue 3. Impala is developed and shipped by Cloudera. Please check the product support matrix for the supported list. Impala Cloudera’s Data Analyst Training course focuses on Apache Hive and Apache Impala. Spark, Hive, Impala and Presto are SQL based engines. Its preferred users are analysts doing ad-hoc queries over the massive data sets stored in Hadoop. 4.2 SP8 deprecated and renamed versions. As an integrated part of Cloudera’s platform, users can run batch processing workloads with Apache Hive, while also analyzing the same data for interactive SQL or machine-learning workloads using tools like Impala or Apache Spark™ — all within a single platform. Cloudera Impala Details Common Hive SQL and interface Unified metadata and scheduler … Apache Hive has provided a familiar and powerful query mechanism for Hadoop users, but query response times are often unacceptable due to Hive’s reliance […] 1. OBIEE 11.1.1.7, Cloudera Hadoop & Hive/Impala Part 2 : Load Data into Hive Tables, Analyze using Hive & Impala. Cloudera Impala is an SQL engine for processing the data stored in HBase and HDFS. Impala can read almost all the file formats such as Parquet, Avro, RCFile used by Hadoop. cloudera takes hadoop security to the next level with sentry fine grained authorization for impala and apache hive 1. Impala uses the same metadata, SQL syntax (Hive SQL), ODBC driver, and user interface (Hue Beeswax) as Apache Hive, providing a familiar and unified platform for batch-oriented or real-time queries. You will learn how to apply traditional data analytics and business intelligence skills to big data. – ZDNet: Cloudera’s Impala Brings Hadoop to SQL and BI (Oct. 25, 2012) – Wired: Marcel Kornacker Profile (Oct. 29, 2012) – Dr. Dobbs: Cloudera Impala – Processing Petabytes at The Speed Of Thought (Oct. 29, 2012) Marcel Kornacker is the architect of Impala. When I try to query the same table from IMPALA, my query returns 0 rows. Go to the Impala Daemon that is used as the coordinator to run the query: https://{impala-daemon-url}:25000/queries The list of queries will be displayed: Click through the “Details” link and then to “Profile” tab: All right, so we have the PROFILE now, let’s dive into the details. Where am I wrong? Impala queries are not translated to MapReduce jobs, instead, they are executed natively. I'm using pure Apache Hadoop with Hive. Apache Hive makes transformation and analysis of complex, multi-structured data scalable in Cloudera environments. Like Apache Drill, Cloudera’s Impala technology seeks to improve interactive query response time for Hadoop users. Apache Impala enables real-time interactive analysis of the data stored in Hadoop using a native SQL environment.

How to determine whether Hive, Impala, an RDBMS, or a mix of these is best for a given task ... multi-structured data scalable in Cloudera environments. Cloudera is a leading Apache Hadoop software and services provider in the big data market. Apache Hive makes multi-structured data accessible to analysts, database administrators, and others without Java programming expertise. Hadoop vendor Cloudera is singing the praises of its own SQL query engine, releasing on Monday the results of a benchmark that shows how Cloudera Impala compares to Apache Hive and a mystery proprietary database.
