Briefly, this error occurs when both a secret token and a shared access token are set in the Elasticsearch configuration. Elasticsearch requires only one type of token for authentication. To resolve this, you should remove either the secret token or the shared access token from the configuration. Ensure that the remaining token is correctly configured and has the necessary permissions. Restart Elasticsearch after making these changes.
This guide will help you check for common problems that cause the log ” Both a secret as well as a shared access token were set. ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: azure, repository-azure, repositories.
Overview
An Elasticsearch snapshot provides a backup mechanism that takes the current state and data in the cluster and saves it to a repository (read 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 can be created per cluster. The following repository types are supported:
Repository types
| Repository type | Configuration type |
|---|---|
| Shared file system | Type: “fs” |
| S3 | Type : “s3” |
| HDFS | Type :“hdfs” |
| Azure | Type: “azure” |
| Google Cloud Storage | Type : “gcs” |
Examples
To register an “fs” repository:
PUT _snapshot/my_repo_01
{
"type": "fs",
"settings": {
"location": "/mnt/my_repo_dir"
}
}Notes and good things to know
- S3, HDFS, Azure and Google Cloud require 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 if you are planning to use the repo type of file system. Otherwise, it will fail.
- When 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 with partial snapshots.
Log Context
Log “Both a secret as well as a shared access token were set.” class name is AzureStorageSettings.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :
final boolean hasKey = Strings.hasText(key);
if (hasSasToken == false && hasKey == false) {
throw new SettingsException("Neither a secret key nor a shared access token was set.");
}
if (hasSasToken && hasKey) {
throw new SettingsException("Both a secret as well as a shared access token were set.");
}
final StringBuilder connectionStringBuilder = new StringBuilder();
connectionStringBuilder.append("DefaultEndpointsProtocol=https").append(";AccountName=").append(account);
if (hasKey) {
connectionStringBuilder.append(";AccountKey=").append(key);
