Final answer:
The preferred replacement for Apache Flume is Apache NiFi (Hortonworks DataFlow), which offers scalability, ease of use, and advanced features for data flow management.
Step-by-step explanation:
The preferred replacement for Apache Flume is often considered to be NiFi, which stands for Apache NiFi (Hortonworks DataFlow). While Flume is a reliable tool designed to collect, aggregate, and move large amounts of log data, it has certain limitations in terms of scalability and ease of use. Apache NiFi, on the other hand, provides a more interactive user interface and supports advanced features such as backpressure, data provenance, and visual command and control, which make it a more versatile and preferred option for data flow management tasks.
