   TIP: To avoid having to specify the fully qualified class name (`org.elasticsearch.hadoop.pig.ESStorage`), consider using a shortcut through http://pig.apache.org/docs/r0.11.1/basic.html#define[`DEFINE`] command:
   
  +[source,sql]
   ----
  -DEFINE ESStorage org.elasticsearch.hadoop.pig.ESStorage('es.resource=radio/artists/');"
  +DEFINE ESStorage org.elasticsearch.hadoop.pig.ESStorage('es.resource=radio/artists/');

negative.code: 
  For example:
  
  [source,sql]
  ----
  LOAD '...' USING ESStorage('<1>es.mapping.names=date:@timestamp<2>, uRL:url<3>')
