HDFS Connection Properties

HDFS Connection Properties

Use a Hadoop File System (HDFS) connection to access data in the Hadoop cluster. The HDFS connection is a file system type connection. You can create and manage an HDFS connection in the Administrator tool, Analyst tool, or the Developer tool. HDFS connection properties are case sensitive unless otherwise noted.
The order of the connection properties might vary depending on the tool where you view them.
The following table describes HDFS connection properties:
Name of the connection. The name is not case sensitive and must be unique within the domain. The name cannot exceed 128 characters, contain spaces, or contain the following special characters:
~ ` ! $ % ^ & * ( ) - + = { [ } ] | \ : ; " ' < , > . ? /
String that the Data Integration Service uses to identify the connection. The ID is not case sensitive. It must be 255 characters or less and must be unique in the domain. You cannot change this property after you create the connection. Default value is the connection name.
The description of the connection. The description cannot exceed 765 characters.
The domain where you want to create the connection. Not valid for the Analyst tool.
The connection type. Default is Hadoop File System.
User Name
User name to access HDFS.
NameNode URI
The URI to access HDFS.
Use the following format to specify the NameNode URI in Cloudera and Hortonworks distributions:
  • <namenode> is the host name or IP address of the NameNode.
  • <port> is the port that the NameNode listens for remote procedure calls (RPC).
Use one of the following formats to specify the NameNode URI in MapR distribution:
  • maprfs:///
  • maprfs:///mapr/
is the cluster name that you specify in the
