Which of the following acts as a sink in Flume?

Apache Flume sink is the component of flume agent. It is used for storing data into a centralized store such as HDFS, HBase, etc. Sink consumes events from the Flume channel and pushes them on to the central repository.

Which sink Stores events into local file system?

File Roll Sink
Answer: The major difference between HDFS FileSink and FileRollSink is that HDFS File Sink writes the events into the Hadoop Distributed File System (HDFS) whereas File Roll Sink stores the events into the local file system.

What is HDFS sink?

The Kafka Connect HDFS 2 Sink connector allows you to export data from Kafka topics to HDFS 2. x files in a variety of formats and integrates with Hive to make data immediately available for querying with HiveQL. This connector is released separately from the HDFS 3.

Which sink writes the event into the Hadoop Distributed File System?

HDFS File Sink
Answer: Basically, HDFS File Sink writes the events into the Hadoop Distributed File System – HDFS while File Roll Sink stores the events into the local file system.

What is source and sink in Flume?

The sink removes the event from the channel and puts it into an external repository like HDFS (via Flume HDFS sink) or forwards it to the Flume source of the next Flume agent (next hop) in the flow. The source and sink within the given agent run asynchronously with the events staged in the channel.

Which of the following is a Flume source?

The article explains different Flume sources like Avro source, Thrift source, Exec source, JMS source, Spooling Directory source, Kafka source, NetCat source, and some more.

What is Flume used for in Hadoop?

Apache Flume is an open-source, powerful, reliable and flexible system used to collect, aggregate and move large amounts of unstructured data from multiple data sources into HDFS/Hbase (for example) in a distributed fashion via it’s strong coupling with the Hadoop cluster.

What is Flume event?

A Flume event is defined as a unit of data flow having a byte payload and an optional set of string attributes. A Flume agent is a (JVM) process that hosts the components through which events flow from an external source to the next destination (hop).

Which of the following functions does Flume support?

Explanation: Flume is used for efficiently collecting, aggregating, and moving large amounts of streaming event data.

Which among the following component of Flume is used to receive data from the data generator?

A source is the component of an Agent which receives data from the data generators and transfers it to one or more channels in the form of Flume events.

What is an event in Flume?

What is Flume source?

Apache Flume source is the component of the Flume agent which receives data from external sources and passes it on to the one or more channels. It consumes data from an external source like a web server. The external data source sends data to Apache Flume in a format that is recognizable by the target Flume source.
