Hi,
I want to get only select fields from ES using Spark ES connector.
I have done some code which is fetching all the documents matching given index
as below:
JavaPairRDD<String, Map<String, Object>> esRDD = JavaEsSpark.esRDD(jsc,
searchIndex);
However, is there a way to only get specific fields from documents for every
index in ES than getting everything ?
Example: Let's say, I have many fields in the documents as below and I have
@timestamp which is also a field in the response { ..............,
@timestamp=Fri Jul 07 01:36:00 IST 2017, ..............}, Here how can I get
the only field @timestamp for all my indexes ?
I could see something here but unable to correlate. can someone help me please ?
Many Thanks!
