Let's looks at some popular open source tools for data ingestion and transfer:
- Apache DistCp: DistCp stands for distributed copy and is part of the Hadoop ecosystem. The DistCp tool is used to copy large data within a cluster or between clusters. DistCp achieves the efficient and fast copying of data by utilizing the parallel processing distribution capability that comes with MapReduce. It distributes directories and files into map tasks to copy files partitions from source to target. DistCp also does error handling, recovery, and reporting across clusters.
- Apache Sqoop: Sqoop is also part of the Hadoop ecosystem project and helps to transfer data between Hadoop and relational data stores such as RDBMS. Sqoop allows you to import data from a structured data store into HDFS and to export data from HDFS into a structured data store. Sqoop uses plugin connectors to connect to relational databases. You can use the Sqoop extension API to build...
