Cdap REST apis for load artifact

[djsharma]

Hi,

I am trying to use cdap rest apis to load artifact jar and json. Some automation i am trying to do thats why not using anyother way. I gone through the document but its not clear where to keep artifact jar and json files and then use the rest api for USER as well as SYSTEM artifacts. 

I kept jar and json in /artifacts of cdap and made rest api request POST /v3/namespaces/<namespace-id>/artifacts/<artifact-name>

as specified in documentation. Response is 400 "Artifact is not in zip format. Please make sure it is a jar file".

Thanks and regards

Dhananjay

Hi Dhananjay,

If you have placed the jar and json in the artifact directory of CDAP, then the artifacts are automatically considered SYSTEM by CDAP and they available across all the namespaces. They will be loaded during the start of the system or you can use the API to trigger the load. 

Here is the API to do so : 

http://docs.cask.co/cdap/current/en/reference-manual/http-restful-api/artifact.html#load-system-artifacts

Note : you dont need load the individual artifact using REST if in artifact directory. 

But, please remember that if you are in development stage of plugin this might be might not be an efficient way. 

Another way is to deploy artifact as USER using the rest APIs in which case the jar and json can be in any directory. Using the API you would upload it to CDAP. 

Could you please the list of files in the artifact directory ?

Thanks,

Nitin

Hi Dhananjay,

> Below are the list of artifacts in directory. I want to load custombox plugin via rest api. Can you help me out to sketch api request for this case.

As Nitin mentioned, if you place the plugin jar and json in artifacts directory - upon restarting CDAP the plugins are automatically loaded. You can also reload the artifacts without having to restart CDAP by hitting the following end point - 

POST v3/namespaces/system/artifacts which is documented here: http://docs.cask.co/cdap/current/en/reference-manual/http-restful-api/artifact.html#load-system-artifacts

Hope it helps. 

Thanks,

Sree
