Explore how Apache Hive provides a SQL-like interface to data in a Hadoop cluster, translating queries into MapReduce jobs, using HCatalog for metadata, and enabling cloud and appliance deployments.
Explore the foundations of Apache Hive and Hadoop, including creating tables, storage locations, data loading, HiveQL basics, and key DML statements, with partitioning and user-defined functions.
Connect to Hive using Beeline to start Hive server 2, run Hive statements, create, show, and drop a sample table, and explore Beeline help for practical, local or remote access.
Learn to use Hue, the Hadoop user experience, via the Beeswax web interface to connect to Hive, authenticate, run queries, and explore tables and history.
Learn how to connect to a hive server using JDBC with a Java program and a shell script. Create and query a table, and load data on localhost:10000.
Create and manage Hive tables by listing, describing, and dropping them, specify default or custom locations, and distinguish Hive managed from external tables, all tracked in the metastore.
Learn how to load data into Hive tables using load data commands, including local inpath and inpath, and understand copy versus move semantics when transferring data in HDFS.
Explore hive's default text record format, with one row per line and a control-a delimiter. Create tables stored as sequence file, avro, parquet, orc, or arrow, and observe json-like schemas.
Explore hive's select enhancements with distribute by and sort by, set reduces to 2, and write results by year to a directory, producing an alphabetized list of countries per year.
Learn to insert data into a Hive table with HiveQL, create a new table, load data with insert into, and compare insert into with insert overwrite and effect on duplicates.
Learn how Hive partitions tables to enable automatic dynamic partitioning, creating per-state directories and a virtual column derived from the directory for fast, easy maintenance and improved performance.
Explore Hive functions, including string concatenation with can_cat, date handling with unix_timestamp, and formatting with from_unixtime, demonstrated on an EU table to merge date and year.
Learn how to create and deploy user defined functions in Hive, packaging custom UDF jars, and applying them to transform data, such as prefixing names and lowering case.
Learn how Hive transform scripts run external tools like rev and an R script on cluster data, using distribute by and sort by, partitioning into five buckets for reduce processing.
Learn how Tez, the Hive execution engine, outperforms MapReduce by avoiding intermediate data writes, enabling faster group by state queries and population sorting on Hortonworks distributions.
Compare mapreduce, tens, and spark as hive execution engines, and see how spark dramatically speeds up a state-by-state population aggregation.
