valid_connection: Validate healthy Elasticsearch connection.

In AlexIoannides/elasticsearchr: A Lightweight Interface for Interacting with Elasticsearch from R

Description

Validates healthy Elasticsearch connections by attempting to call the cluster healthcheck endpoint. In doing to, it defends against incorrect URLs to Elasticsearch clusters. Requires that URLs point directly to a master node - i.e. the endpoint that would return the default Elasticsearch message, "You Know, for Search", e.g. 'http://localhost:9200'.

Usage

valid_connection(url)

Arguments

url	The URL to validate.

Value

Boolean

Examples

## Not run: 
url <- "http://localhost:9200"
valid_connection(url)
# TRUE

url <- "http://localhost:9201"
valid_connection(url)
#  Error: Failed to connect to localhost port 9201: Connection refused

## End(Not run)
