Description

This ticket totally eliminates the need for an external service to host the jars. So a url will no longer be required. An external URL leads to unreliability because the service may go offline or it can be DDoSed if/when too many requests are sent to them

 

 
Add a jar to cluster as follows

curl -X POST -H 'Content-Type: application/octet-stream' --data-binary @myjar.jar http://localhost:8983/api/cluster/filestore/package?name=myjar.jar

This does the following operations

• Upload this jar to all the live nodes in the system
• The name of the file is the sha256-<name> of the file/payload
• The store is agnostic of the content of the file/payload

 How it works?

A blob that is POSTed to the /api/cluster/blob end point is persisted locally & all nodes are instructed to download it from this node or from any other available node. If a node comes up later, it can query other nodes in the system and download the blobs as required

add package command

curl -X POST -H 'Content-type:application/json' --data-binary '{
  "add": {
       "name": "my-package" ,
      "file":{"id" : "<the-sha256>", "sig" : "<signature>"}
  }}' http://localhost:8983/api/cluster/package
