We added checksum verification to `@kbn/es` in https://github.com/elastic/kibana/pull/33893, which is working, and in turn proves that using the Artifact API to download snapshots wasn't enough to fix the issues we've been seeing. In https://kibana-ci.elastic.co/job/elastic+kibana+7.0/412/JOB=kibana-ciGroup8,node=immutable/console we see: ``` 00:14:20.762 │ info Installing from snapshot 00:14:20.763 │ info version: 7.0.0 00:14:20.763 │ info install path: /var/lib/jenkins/workspace/elastic+kibana+7.0/JOB/kibana-ciGroup8/node/immutable/kibana/.es/test-97zzlri1nyb 00:14:20.764 │ info license: oss 00:14:20.764 │ info downloading artifact info from https://artifacts-api.elastic.co/v1/versions/7.0.0-SNAPSHOT/builds/latest/projects/elasticsearch 00:14:20.852 │ info downloading artifact from https://snapshots.elastic.co/7.0.0-ea741e68/downloads/elasticsearch/elasticsearch-oss-7.0.0-SNAPSHOT-linux-x86_64.tar.gz 00:14:22.765 │ info downloading artifact checksum from https://snapshots.elastic.co/7.0.0-ea741e68/downloads/elasticsearch/elasticsearch-oss-7.0.0-SNAPSHOT-linux-x86_64.tar.gz 00:14:22.818 00:14:22.818 artifact downloaded from https://snapshots.elastic.co/7.0.0-ea741e68/downloads/elasticsearch/elasticsearch-oss-7.0.0-SNAPSHOT-linux-x86_64.tar.gz does not match expected checksum 00:14:22.819 expected: 1e5188c1410e0299777dd1cb9638aa12de4067ea80a77ff6723986746bbc7b1a35d580023f605e6e1ae84887e675ba10184032da80240a42289ee6c5d5361c66 00:14:22.820 received: 7630553ab83828196931917aa15f17bf1f31d541fd11e0f1c82d89f294fbe47dca7be99d96da5baa0a9545712e3c9340f9b3d989e5056a3f9471f43bb582becc ``` The new logging shows that we used the explicit URL for the artifact `https://snapshots.elastic.co/7.0.0-ea741e68/downloads/elasticsearch/elasticsearch-oss-7.0.0-SNAPSHOT-linux-x86_64.tar.gz` and still got invalid data, which confirms our suspicion that something funky is happening with the CDN. In order to understand more about what's going on here this PR adds a buffer that caches the first 500 bytes from the artifact response and will log it in utf8 format if the checksum doesn't match. I'm hoping we're going to see some HTML or something that will help explain what's happening. |

Using a Kibana Release
If you want to use a Kibana release in production, give it a test run, or just play around:
- Download the latest version on the Kibana Download Page.
- Learn more about Kibana's features and capabilities on the Kibana Product Page.
- We also offer a hosted version of Kibana on our Cloud Service.
Building and Running Kibana, and/or Contributing Code
You might want to build Kibana locally to contribute some code, test out the latest features, or try out an open PR:
- CONTRIBUTING.md will help you get Kibana up and running.

Documentation
Visit Elastic.co for the full Kibana documentation.
For information about building the documentation, see the README in elastic/docs.
Version Compatibility with Elasticsearch
Ideally, you should be running Elasticsearch and Kibana with matching version numbers. If your Elasticsearch has an older version number or a newer major number than Kibana, then Kibana will fail to run. If Elasticsearch has a newer minor or patch number than Kibana, then the Kibana Server will log a warning.
Note: The version numbers below are only examples, meant to illustrate the relationships between different types of version numbers.
| Situation | Example Kibana version | Example ES version | Outcome |
|---|---|---|---|
| Versions are the same. | 5.1.2 | 5.1.2 | 💚 OK |
| ES patch number is newer. | 5.1.2 | 5.1.5 | ⚠️ Logged warning |
| ES minor number is newer. | 5.1.2 | 5.5.0 | ⚠️ Logged warning |
| ES major number is newer. | 5.1.2 | 6.0.0 | 🚫 Fatal error |
| ES patch number is older. | 5.1.2 | 5.1.0 | ⚠️ Logged warning |
| ES minor number is older. | 5.1.2 | 5.0.0 | 🚫 Fatal error |
| ES major number is older. | 5.1.2 | 4.0.0 | 🚫 Fatal error |
