Introduction to Project11:56
Learn to import data from RDBMS to HDFS using Sqoop, with joins, filters, and ordering. Master Sqoop jobs, direct Hive imports, handling nulls, and data compression.

Basic Sqoop Cammand Part 17:48
Learn to craft a Sqoop import using a password file, connect via JDBC to MySQL HR analytics, import employee data, and manage map-only jobs with mappers and the warehouse directory.
Basic Sqoop Cammand Part 25:47
Demonstrates using Sqoop to import rdbms data from MySQL to HDFS via a warehouse directory, with one mapper, importing all tables such as employee, general, and manager data.
Basic Sqoop Cammand Part 35:23
Execute Sqoop import all tables with -m 1 to create a single file in HDFS, using scope import with exclude to skip employee data and produce general data and manager data.
Basic Sqoop Cammand Part 42:26
Exclude multiple tables in Sqoop by listing them after a comma, so only the manager data table imports from the RDBMS to HDFS.

Salary Analysis Subset Import10:57
Explore Sqoop subset imports by selecting specific columns (employee id, name, department, job role, monthly income) with a where clause and a SQL query for precise data in HDFS.
Salary Analysis Subset Import Continue2:27
Explore how to use split by and dollar conditions in Sqoop import to transfer data chunks, run an SQL query, and verify five records.
Attrition Analysis Complex JOIN9:05
Analyze attrition with a complex join of general and employee data, focusing on number of companies worked, years at the company, and job satisfaction, then import via Sqoop.

Sqoop Jobs7:34
Learn to create and run Sqoop jobs within Oozie workflows to import data and analyze promotions this year using years since last promotion equals zero.
Sqoop Jobs Continue10:09
Learn how to build a scope job in Sqoop that joins general and employee datasets to analyze a 12 percent salary hike and job satisfaction.
NULL Value Handling10:09
Discover how to import data with Sqoop from MySQL to a Hive table and handle null values, using null non string or null string replacements and a default value.
Data Formats and Compression4:26
Learn to import data with Sqoop in Avro and sequence file formats, and apply compression to optimize HDFS storage.

Requirements

Basic knowledge of Hadoop and relational databases.
Familiarity with SQL commands is beneficial but not mandatory.
A system with Hadoop installed or access to a cloud-based Hadoop environment.
