Configure the destination like this:

Hadoop FS tab:

Hadoop FS URI: you can leave this empty if SDC should use the default file system connection from the configuration files loaded below. Otherwise, for Hadoop FS specify a URI of the form hdfs://hostname/ and for MapR FS, maprfs:///mapr/my.cluster.com/.

HDFS User: an appropriate HDFS username

Kerberos Authentication: you should enable this if your Hadoop environment is secured

Hadoop FS Configuration Directory: you may need to change this to suit your environment. This directory must contain the core-site.xml and hdfs-site.xml configuration files.

Output Files tab:

Data Format: Avro

Directory in Header: Enabled

Max Records in File: 1

Use Roll Attribute: Enabled

Roll Attribute Name: roll

Note - the destination will continue writing to a file until the first of these five conditions is satisfied:

The number of records specified in ‘Max Records in File’ has been written (zero means there is no maximum)

The specified ‘Max File Size’ has been reached (again, zero means there is no maximum)

No records have been written for the specified ‘Idle Timeout’

A record with the specified roll header attribute is processed
