I want to evaluate Grafana with ElasticSearch. The creation of a data source in Grafana is not a problem. On the other hand, querying the data source via KNOX requires passing requests with a "content-type" = "application/octet-stream" while Grafana sends requests with a "content-type" = "application/json".
Indeed, in this mode, the "\n" are deleted by KNOX before being communicated to data source, except that these are important for data source to correctly interpret the query.
Is it possible to change this behavior on the KNOX side? any other solution.
