  - Flume
    - Configuring Flume
      - Configure a Secure HBase Sink
      - Configure a Secure File System Sink
        When writing to the file system on a secure data-fabric cluster, you must configure Flume agents to use either a user ticket or a Kerberos ticket.
      - Flume Thrift Security Parameters
        On a secure cluster, SSL for Flume Thrift Source and Sink is automatically configured.
      - Configure User Impersonation for Flume
        Configure impersonation for Flume agents to allow one user (the mapr super user) to access data and submit jobs on behalf of another user.
      - Integrate Flume with HPE Ezmeral Data Fabric Streams
        Integrate Flume 1.6 with HPE Ezmeral Data Fabric Streams when you want to write Flume source data to a HPE Ezmeral Data Fabric Streams topic or when you want to write HPE Ezmeral Data Fabric Streams topics to a Flume sink.

Integrate Flume with HPE Ezmeral Data Fabric Streams

Integrate Flume 1.6 with HPE Ezmeral Data Fabric Streams when you want to write Flume source data to a HPE Ezmeral Data Fabric Streams topic or when you want to write HPE Ezmeral Data Fabric Streams topics to a Flume sink.

IMPORTANT This component is deprecated. Hewlett Packard Enterprise recommends using an alternate product. For more information, see Discontinued Ecosystem Components.

You can use Flume and HPE Ezmeral Data Fabric Streams for many different use cases; however, here are a few examples:

Write HPE Ezmeral Data Fabric Streams topics to file on the MapR filesystem: To write HPE Ezmeral Data Fabric Streams topics to the MapR filesystem, create an agent with a Kafka source and a HDFS sinks.
Write HPE Ezmeral Data Fabric Streams topics to HPE Ezmeral Data Fabric Database: To write HPE Ezmeral Data Fabric Streams topics to HPE Ezmeral Data Fabric Database, create an agent with a Kafka source and a HPE Ezmeral Data Fabric Database sink.
Write data from any supported Flume source to HPE Ezmeral Data Fabric Streams topics: To write data from any supported Flume source to HPE Ezmeral Data Fabric Streams topics, create an agent with the appropriate Flume source type and a Kafka sink or Kafka channel. For example, you can use a syslogs source to turn logs into a MapR stream topic.

NOTE Before you integrate Flume with HPE Ezmeral Data Fabric Streams, verify that the Streams Client is installed on all Flume nodes. For more information, see Installing Flume.
