public class ToVoid
extends Driver

This class provides converting data set descriptions to data set descriptions in VoID format. This is no MapReduce job. All the cluster description data will be processed by the namenode of the Hadoop cluster.

The following table lists the properties necessary to set.

property name description example value
de.hpi.fgis.voidgen.hadoop.tasks.ToVoid.input_paths Contains the descriptions of the data sets in sequence file format. voidGen/void_descriptions
de.hpi.fgis.voidgen.hadoop.tasks.ToVoid.hdfs_output_path Optional. The path for saving data set descriptions in void format in HDFS. voidGen/VoID_d.txt
de.hpi.fgis.voidgen.hadoop.tasks.ToVoid.s3_output_path Optional. The path for saving data set descriptions in void format in amazon s3. s3n://my.bucket/voidgen/descriptions.txt
de.hpi.fgis.voidgen.hadoop.tasks.ToVoid.local_output_path Optional. The path for saving data set descriptions in void format on the name node's local file system. voidGen/descriptions.txt
