elasticsearch-httpclient's Introduction

HTTP Client call example

This project is a demo project which reproduces a Security Manager issue when we run the plugin in the context of Elasticsearch as a plugin.

It uses Elasticsearch 6.0.0.

To reproduce:

mvn clean install

Install elasticsearch 6.0.0
Remove the existing plugin and install the new one:

bin/elasticsearch-plugin remove httpclient
bin/elasticsearch-plugin install file:///path/to/elasticsearch-httpclient/target/releases/httpclient-1.0-SNAPSHOT.zip

Start elasticsearch:

bin/elasticsearch

Call the REST Endpoint

curl 127.0.0.1:9200?pretty
curl 127.0.0.1:9200/_bano?pretty
