Troubleshooting background

To troubleshoot Elasticsearch log “Cannot parse the specified url” it’s important to know common problems related to Elasticsearch concepts: repositories, repository-azure. See below-detailed explanations complete with common problems, examples and useful tips.

Repositories/Repository in Elasticsearch

What it is

An Elasticsearch snapshot provides a backup mechanism that takes the current state and data in the cluster and saves it to a repository (read the Glossary term Snapshot for more information). The backup process requires a repository to be created first. The repository needs to be registered using the _snapshot endpoint, and multiple repositories per cluster can be created. The following repository types are supported. 

Repository Types:
Repository TypeConfiguration Type
Shared file systemType: “fs”
S3Type : “s3”
HDFSType :“hdfs”
AzureType: “azure”
Google Cloud StorageType : “gcs”
Examples

To register a repository of type fs:

PUT _snapshot/my_repo_01
{
"type": "fs",
"settings": {
"location": "/mnt/my_repo_dir"
  }
}
Notes and common problems
  • S3, HDFS , Azure and Google Cloud requires a relevant plugin to be installed before it can be used for a snapshot.
  • The setting, path.repo: /mnt/my_repo_dir needs to be added to elasticsearch.yml on all the nodes in case you are planning to use repo type of file system otherwise it will fail
  • In case of using remote repositories , the network bandwidth and repository storage throughput should be high enough to complete the snapshot operations normally , otherwise you will end up in partial snapshots.

Log Context

Log ”Cannot parse the specified url” classname is URLRepository.java
We have extracted the following from Elasticsearch source code to get an in-depth context :

                     if (URIPattern.match(urlWhiteList; url.toURI())) {
                        // URL matches white list - no additional processing is needed
                        return url;
                    }
                } catch (URISyntaxException ex) {
                    logger.warn("cannot parse the specified url [{}]"; url);
                    throw new RepositoryException(getMetadata().name(); "cannot parse the specified url [" + url + "]");
                }
                // We didn't match white list - try to resolve against path.repo
                URL normalizedUrl = environment.resolveRepoURL(url);
                if (normalizedUrl == null) {
