what can I do with hadoop and elasticsearch together?

I'm reading about hadoop with elasticsearch, so I'm confused about how it works.

I guess in this case elasticsearch is substitute for HDFS/Hbase, so I could write hadoop jobs to get and process data in elasticsearch.

Is this correct?

If yes, does this works for Hive and Pig too?

You can use elasticsearch in Hadoop like :

  • Input and output for MapReduce
  • Input (storage) for Hive and Pig
  • Write and read directly in ElasticSearch with Cascading
