Skills measured

Pig Latin is a high-level programming language used to analyze large datasets in Hadoop. Candidates should have a strong understanding of Pig Latin syntax, including the ability to write and execute Pig scripts. It is crucial to assess this sub-skill as it forms the foundation of Pig programming and is essential for working with large datasets.

Candidates should be able to transform data using Pig Latin, including filtering, sorting, and joining data sets. They should also be able to perform data cleaning and data validation tasks. Assessing this sub-skill is crucial as data transformation is a critical step in the data analysis process.

Candidates should be familiar with Pig Latin functions, including built-in functions and user-defined functions. They should be able to use these functions to perform complex data analysis tasks. Assessing this sub-skill is crucial as functions are an essential part of Pig programming and are used to perform a wide range of data analysis tasks.

Candidates should be able to debug and optimize Pig scripts to improve performance and efficiency. They should be able to identify and fix errors in Pig scripts and optimize the scripts for better performance. Assessing this sub-skill is crucial as debugging and optimization are essential for working with large datasets and improving the efficiency of data analysis tasks.

Candidates should be familiar with the different execution modes in Pig, including local mode, map-reduce mode, and tez mode. They should be able to choose the appropriate execution mode based on the requirements of the data analysis task. Assessing this sub-skill is crucial as the choice of execution mode can have a significant impact on the performance and efficiency of data analysis tasks.

Candidates should be able to write and use Pig User-Defined Functions (UDFs) to perform custom data analysis tasks. They should be able to write UDFs in Java or Python and integrate them into Pig scripts. Assessing this sub-skill is crucial as UDFs are an essential part of Pig programming and are used to perform custom data analysis tasks that cannot be performed using built-in functions.
