Examples of EsTap

org.elasticsearch.hadoop.cascading.EsTap
Cascading Tap backed by ElasticSearch. Can be used as a source and/or sink, for both local and Hadoop (local or not) flows. If no fields are specified or are associated with the incoming tuple, the Tap will create name each field "field[num]" - this allows the document to be parsed by ES but will most likely conflict with the existing mapping for the given index.
