Descripción

Cloudera University’s four-day Data Analyst Training course will teach you to apply traditional data analytics and business intelligence skills to big data. This course presents the tools data professionals need to access, manipulate, transform, and analyze complex data sets using SQL and familiar scripting languages.
Advance Your Ecosystem Expertise.
Apache Hive makes transformation and analysis of complex, multi-structured data scalable in Cloudera environments. Apache Impala enables real-time interactive analysis of the data stored in Hadoop using a native SQL environment. Together, they make multi-structured data accessible to analysts, database administrators, and others without Java programming expertise.

Objetivos

Through instructor-led discussion and interactive, hands-on exercises, participants will navigate the ecosystem, learning:

  1. How the open source ecosystem of big data tools addresses challenges not met by traditional RDBMSs
  2. Using Apache Hive and Apache Impala to provide SQL access to data
  3. Hive and Impala syntax and data formats, including functions and subqueries
  4. Create, modify, and delete tables, views, and databases; load data and store results of queries
  5. Create and use partitions and different formats.
  6. Combining two or more datasets using JOIN or UNION, as appropriate
  7. What analytic and windowing functions are, and how to use them
  8. Store and query complex or nested data structures
  9. Process and analyze semi-structured and unstructured data
  10. Techniques for optimizing Hive and Impala queries
  11. Extending the capabilities of Hive and Impala using parameters, custom file formats and SerDes, and external scripts
  12. How to determine whether Hive, Impala, an RDBMS, or a mix of these is best for a given task
