Data Model

This processor executes an Apache Flume source. Each Flume Event is turned into a FlowFile. The content of the FlowFile is set to the body of the Event and the Event headers become FlowFile attributes.

Configuration Details

This processor is designed to execute arbitrary Flume sources. Most of the details of configuring the source is deferred to Flume's built-in configuration system. For details on the available settings for each source type, refer to the Flume User Guide. Configuring the Flume source is a four step process:

  1. Set the Source Type property to a valid Flume source type.
  2. Set the Agent Name property to the name of the agent in your Flume configuration. This is the prefix of the properties in the Flume configuration file. Example: tier1
  3. Set the Source Name property to the name of the source in your Flume configuration. If Agent Name is tier1, then the Source Name is the value of the tier1.sources property. Example: src-1
  4. Copy and paste the configuration for the source from your Flume configuration file into the Flume Configuration property. Assuming you're using the same Agent Name and Source Name as in the examples above, this will be all of the properties that start with tier1.sources.src-1. Do not copy the tier1.sources.src-1.type or properties.

Usage Example

Assuming you had the following existing Flume configuration file:

a1.sources = r1
a1.sinks = k1
a1.channels = c1

a1.sources.r1.type = multiport_syslogtcp
a1.sources.r1.channels = c1 =
a1.sources.r1.ports = 10001 10002 10003
a1.sources.r1.portHeader = port

a1.sinks.k1.type = logger

a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

a1.sources.r1.channels = c1 = c1

Then you'd configure the ExecuteFlumeSource as follows:

Property Value
Source Type multiport_syslogtcp
Agent Name a1
Source Name r1
Flume Configuration =
a1.sources.r1.ports = 10001 10002 10003
a1.sources.r1.portHeader = port
