Sending data to elasticsearch with json file using CURL, meet records number limitation

Hi All,

I want to using json file to send data to elasticsearch with curl, but got problem with limited records number in json file.

Elasticsearch version: 5.6.2, Memory: 16G, Single node with 5 shards.

using: curl -XPOST '' --data-binary @test3.json

the result is ok, and test3.json file contains 3 reocrds, the file size is 1KB.

using: curl -XPOST '' --data-binary @test4.json

the result is error, detail information as below, test4.json file contains 4 records, the file size is .1.3KB.

Some possible problems are:

  • Missing or unknown request method.

  • Missing URL.

  • Missing HTTP Identifier (HTTP/1.0).

  • Request is too large.

  • Content-Length missing for POST or PUT requests.

  • Illegal character in hostname; underscores are not allowed.

  • HTTP/1.1 Expect: feature is being asked from an HTTP/1.0 software.

What is the log? What is the exact message?

Had similar issue. If you are using proxy, try disabling proxy, which worked for me.
