This guide will help you check for common problems that cause the log ” Unable to delete global metadata file ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: blobstore, delete, discovery-file, metadata and repositories.

Overview
DELETE is an Elasticsearch API which removes a document from a specific index. This API requires an index name and _id document to delete the document.
Delete a document
DELETE /my_index/_doc/1
Notes
- A delete request throws 404 error code if the document does not already exist in the index.
- If you want to delete a set of documents that matches a query, you need to use delete by query API.
