Apache Hive is a data warehouse system that summarizes data, facilitates ad-hoc queries, and analyzes large data sets stored in Hadoop-compatible file systems. It provides a mechanism to project structure on this data and to query data using a SQL-like language called HiveQL. This language als...
Hive is a data warehouse infrastructure built on top of Hadoop. It provides tools to enable easy data ETL, a mechanism to put structures on the data, and the capability to querying and analysis of large data sets stored in Hadoop files. Hive defines a simple SQL-like query language, calle...
Hive provides a mechanism to put structure on 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...

Hive is a data warehouse infrastructure based on Hadoop, which provides a SQL-like querying language called HQL (Hive Query Language) for processing large-scale datasets. Creating temporary tables and inserting data is a common operation in Hive, and this article will provide a detailed guide on...
CONCAT ('Intellipaat','-','is','-','a','-','eLearning',’-’,’provider’); Output: Intellipaat-is-a-eLearning-provider Every time, we set the limits of the strings by ‘-‘. If it is common for every string, then Hive provides another command: CONCAT_WS In this case, we ...

Hive is a data warehouse infrastructure built on top ofHadoop. It provides tools to enable easy dataETL, a mechanism to put structures on the data, and the capability to querying and analysis of large data sets stored in Hadoop files. Hive defines a simple SQL-like query language, called ...
Hive provides the following functions: Analyzes massive structured data and summarizes analysis results. Allows complex MapReduce jobs to be compiled in SQL languages. Supports flexible data storage formats, including JavaScript object notation (JSON), comma separated values (CSV), TextFile, RCFile, ...
