Change the delimiter and file format of data during import using Sqoop
Ingest real-time and near-real-time streaming data into HDFS
Process streaming data as it is loaded onto the cluster
Load data into and out of HDFS using the Hadoop File System commands

Transform, Stage, and Store

Convert a set of data values in a given format stored in HDFS into new data values or a new data format and write them into HDFS.

Load RDD data from HDFS for use in Spark applications
Write the results from an RDD back into HDFS using Spark
Read and write files in a variety of file formats
Perform standard extract, transform, load (ETL) processes on data

Data Analysis

Use Spark SQL to interact with the metastore programmatically in your applications. Generate reports by using queries against loaded data.

Use metastore tables as an input source or an output sink for Spark applications
Understand the fundamentals of querying datasets in Spark
Filter data using Spark
Write queries that calculate aggregate statistics
Join disparate datasets using Spark
Produce ranked or sorted data
