Hi,

I want to post data to external service using curl command from Pig. Is it possible to run curl command from Pig?

@priyal patel,

Yes. You can run curl command in pig. You can run shell commands in pig using "sh {command}"

Here is the sample.

[root@test-instance-1 ~]$ pig
grunt> sh curl -k -u admin:admin -H "X-Requested-By:ambari" http://localhost:8080/api/v1/clusters
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
{
  "href" : "http://localhost:8080/api/v1/clusters",
  "items" : [  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
    {
100   236  100   236    0     0   3808      0 --:--:-- --:--:-- --:--:--  3868      "href" : "http://localhost:8080/api/v1/clusters/cl1",
      "Clusters" : {
        "cluster_name" : "cl1",
        "version" : "HDP-2.6"
      }
    }
  ]
}
