(I'm using this image: amazon/opendistro-for-elasticsearch:1.13.2) Following the docs on setting up an azure repository: 1. Added storage account name and key and reloaded settings ([Azure Repository | Elasticsearch Plugins and Integrations [7.10] | Elastic](https://www.elastic.co/guide/en/elasticsearch/plugins/7.10/repository-azure-usage.html)) ```auto # on the elasticsearch node; I have one node in this test cluster bin/elasticsearch-keystore add azure.client.default.account bin/elasticsearch-keystore add azure.client.default.key curl -X POST "localhost:9200/_nodes/reload_secure_settings" ``` 1. Tried to register the Azure repository using the simplest settings ([Repository settings | Elasticsearch Plugins and Integrations [7.10] | Elastic](https://www.elastic.co/guide/en/elasticsearch/plugins/7.10/repository-azure-repository-settings.html)) ```auto # on the elasticsearch node curl -X PUT "localhost:9200/_snapshot/my_backups_repository" -H 'Content-Type: application/json' -d '{ "type": "azure" }' ``` Getting ```auto { "error": { "root_cause": [ { "type": "repository_verification_exception", "reason": "[my_backups_repository] path is not accessible on master node" } ], "type": "repository_verification_exception", "reason": "[my_backups_repository] path is not accessible on master node", "caused_by": { "type": "null_pointer_exception", "reason": "Cannot invoke \"String.length()\" because \"host\" is null" } }, "status": 500 } ``` and in the logs I see ```auto [2021-09-10T13:50:42,456][WARN][r.suppressed] [elasticsearch-0] path: /_snapshot/my_backups_repository, params: {repository=my_backups_repository} org.elasticsearch.repositories.RepositoryVerificationException: [my_backups_repository] path is not accessible on master node at org.elasticsearch.repositories.blobstore.BlobStoreRepository.startVerification(BlobStoreRepository.java:1276) ~[elasticsearch-7.10.2.jar:7.10.2] at org.elasticsearch.repositories.RepositoriesService$3.doRun(RepositoriesService.java:268) ~[elasticsearch-7.10.2.jar:7.10.2] at org.elasticsearch.common.util.concurrent.ThreadContext$ContextPreservingAbstractRunnable.doRun(ThreadContext.java:743) [elasticsearch-7.10.2.jar:7.10.2] at org.elasticsearch.common.util.concurrent.AbstractRunnable.run(AbstractRunnable.java:37) [elasticsearch-7.10.2.jar:7.10.2] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1130) [?:?] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:630) [?:?] at java.lang.Thread.run(Thread.java:832) [?:?] Caused by: java.lang.NullPointerException: Cannot invoke "String.length()" because "host" is null at com.microsoft.azure.storage.core.Utility.isHostDnsName(Utility.java:533) ~[?:?] at com.microsoft.azure.storage.core.Utility.determinePathStyleFromUri(Utility.java:521) ~[?:?] at com.microsoft.azure.storage.StorageUri.(StorageUri.java:71) ~[?:?] at com.microsoft.azure.storage.core.PathUtility.appendPathToUri(PathUtility.java:124) ~[?:?] at com.microsoft.azure.storage.core.PathUtility.appendPathToUri(PathUtility.java:108) ~[?:?] at com.microsoft.azure.storage.blob.CloudBlobContainer.(CloudBlobContainer.java:169) ~[?:?] at com.microsoft.azure.storage.blob.CloudBlobClient.getContainerReference(CloudBlobClient.java:123) ~[?:?] at org.elasticsearch.repositories.azure.AzureBlobStore.writeBlob(AzureBlobStore.java:333) ~[?:?] at org.elasticsearch.repositories.azure.AzureBlobContainer.writeBlob(AzureBlobContainer.java:115) ~[?:?] at org.elasticsearch.repositories.azure.AzureBlobContainer.writeBlobAtomic(AzureBlobContainer.java:123) ~[?:?] at org.elasticsearch.repositories.blobstore.BlobStoreRepository.startVerification(BlobStoreRepository.java:1271) ~[elasticsearch-7.10.2.jar:7.10.2] ... 6 more ``` Can't figure out what `host` might refer to. Are there more settings I need to provide? ---

> [@margold](#): > > (I'm using this image: amazon/opendistro-for-elasticsearch:1.13.2) opendistro is an aws project, you may need to ask them on their support forums. However, did you create a custom `container` or are you using the default? ---

I tried both the default container (`elasticsearch-snapshots` based on what the docs say) and a custom container (`backups`) ```auto # checking that the containers exist az storage container list --account-name xyz -o table Name Lease Status Last Modified ----------------------- -------------- ------------------------- backups 2021-08-19T11:22:07+00:00 elasticsearch-snapshots 2021-09-13T13:26:02+00:00 ``` ```auto PUT _snapshot/my_backups_repository { "type": "azure" } PUT _snapshot/my_backups_repository { "type": "azure", "settings": { "container": "backups", } } ``` ---

You might need to ask the opendistro devs then sorry. ---

So turns out I had a typo in the container name. After fixing that, everything works. Just leaving this here in case anybody else has the same problem as `Cannot invoke \"String.length()\" because \"host\" is null` is not the clearest error message. ---
