No silos. Hive environment. In addition to using the same unified storage platform, Impala also uses the same metadata, SQL syntax (Hive SQL), ODBC driver and user interface (Hue Beeswax) as Apache Hive. Reference Architecture Dell EMC Isilon and Cloudera Reference Architecture and Performance Results Abstract This document is a high-level design, performance results, and best-practices guide for deploying Cloudera Enterprise Distribution on bare-metal infrastructure with Dell EMC’s Isilon scale-out NAS solution as a shared storage backend. Through these experiments, we attempted to show that how data is structured (in effect, data modeling) is just as important in a big data environment as it is in the traditional database world. In this post we will close the loop on BDR replication and review how to setup and integrate Hive replication Now we are going to discuss Hive Architecture in detail. From hivecommandline: [cloudera@quickstart ~]$ hive -e '!env'|grep HIVE_HOME HIVE_HOME=/usr/lib/hive From hive shell - this will print same variables as above but you can't use grep here, so you will have to find HIVE_HOME from list of all variables:. This allows users to easily read and write data without worrying about where the data is stored, what format it is, or redefining the structure for each tool. This component implements the notion of session handles and provides execute and fetch APIs modeled on JDBC/ODBC interfaces. The goal is to have three separate "landing" zones in Hadoop that will feed into each Oracle database, respectively, i.e. CDH is based entirely on open standards for long-term architecture. The architecture of Impala is very simple, unlike Hive. To access hive managed tables from spark Hive Warehouse […] Using HCatalog, a table and storage management layer for Hadoop, Hive metadata is exposed to other data processing tools, including Pig and MapReduce, as well as through a REST API.

Structure can be projected onto data already in storage. Apache Hive was one of the first projects to bring higher-level languages to Apache Hadoop.Specifically, Hive enables the legions of trained SQL users to use industry-standard SQL to process their Hadoop data. The Impala server is a distributed, massively parallel processing (MPP) database engine. The defaults from Cloudera Manager were used to setup / configure Impala 2.6.0. Hive also benefits from unified resource management (through YARN), simple deployment and administration (through Cloudera Manager), and shared compliance-ready security and governance (through Apache Sentry and Cloudera Navigator) —- all critical for running in production. Hive Warehouse Connector (HWC) was available to provide access to managed tables in hive from spark, however since this involved communication with LLAP there was an additional hop to get the data and process it in spark vs the ability of spark to directly read the data from FileSystem for External tables.
