hadoop and lazarus
« on: December 01, 2017, 10:10:51 am »
Hi guys, I'm starting to interest in the big date concept! And looking a little on the net I saw that Apache hadoop exists, but it seems that to be able to use it you have to have solid java bases. What I do not have. Do any of you use hadoop and know more information about it? I think the big dates in the future will take up a lot of workplace space. I would like to know if it is possible to somehow interact in hadoop with lazarus and not with java. Thank you

hi, did you consider a REST approach?

I never used rest with lazarus. You can indicate a good component or a specific library. Especially to read the result

i use standard library (fphttpclient, fpjson, jsonparser):

Code: Pascal  [Select][+][-]
  1. HTTPRequest := TFPHttpClient.Create(nil);
  2. ResponseContent := HTTPRequest.Get(AURL);
  3. JSON := GetJSON(ResponseContent);

with GET and POST i do not have issues.
