Hello All,  
Can we use Java to only read data from elasticsearch that we are already ingested logs file to elasticsearch?  
not to index from java and retrieving, only to read already created logs file's instead of kibana to get as JSON from java?

or else any other way?

Yes.

Although I'm not quite I understood what you meant by "read data from elasticsearch"...

Do you mean search? To you mean extract all data that matches a search?  
Anyway, this is all possible with the Java Rest Client.
