Its convenient sometimes to partition logs by date values or other e.g.

PathPartitionHelper

Implements the logic for: Listing partition keys and values used in an hdfs path Filtering of partitions from a pig filter operator expression Restrictions Function calls are not supported by this partition helper and it can only handle String values. This is normally not a problem given that partition values are part of the hdfs folder path and is given a determined value that would not need parsing by any external processes.
