This property specifies where cuboid replication should take place. Local stores cuboids on the local disk of each query engine. NFS will replicate the cuboids in a shared location for all Query Engines and None will not replicate any cuboids.

Values and behavior:

  • None: Cuboids will be pulled from HDFS and no replication will take place.
  • Local: Cuboids are replicated on local disks on the Query Engine machine.
  • NFS: Cuboids are replicated in the Networked File System.

Default value:



  • Connection: If the property is set at the connection, then the property value is applicable for all dataset build and cube build jobs.
  • Cube: If the property is set on a cube, then the value will override the connection level value for that cube’s build job.

Comes into effect:

The value of the property can be changed at any time and will be respected on restart or during the periodic cleanup process.

In systems that have available space on a local disk, local replication is recommended. This prevents the need to pull from HDFS or NFS which saves disk transfer time.
