I want to install the CCR (Cross-Cluster Replication) plugin on a custom OpenSearch instance, but it's not working

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
I downloaded OpenSearch 3.0.0 snapshot from GitHub.

Describe the issue:
When I tried to download and install the CCR (Cross-Cluster Replication) plugin version 2.9.0 using the bin/opensearch-plugin install command, it failed due to version incompatibility.

[root@871398ffa22d opensearch]# bin/opensearch-plugin install https://repo1.maven.org/maven2/org/opensearch/plugin/opensearch-cross-cluster-replication/2.9.0.0/opensearch-cross-cluster-reption-2.9.0.0.zip

I downloaded the OpenSearch Cross-Cluster Replication (CCR), assembled it, and attempted to install the plugin from the resulting zip file. However, an error occurred during the installation process.

Hi @sbilac ,

Could you please send the URL where you found the OpenSearch 3.0.0 snapshot?

Hi @Eugene7.

I cloned the OpenSearch GitHub repository directly, made modifications, and deployed a custom OpenSearch instance using Docker.

Currently, I’m following the guidance from this post to resolve the issue:

github.com/NLPchina/elasticsearch-sql

plugin-descriptor.properties: Not a directory

opened 08:31AM - 08 Mar 16 UTC

beta-beta

I download zip from the link: https://github.com/NLPchina/elasticsearch-sql/rele…ases/download/2.1.0.1/elasticsearch-sql-2.1.0.1.zip but there is some trouble: Verifying file:/data1/elasticsearch/elasticsearch-2.1.0-node-2/plugins/elasticsearch-sql-2.1.0.1.zip checksums if available ... NOTE: Unable to verify checksum for downloaded plugin (unable to find .sha1 or .md5 file to verify) ERROR: /data1/elasticsearch/elasticsearch-2.1.0-node-2/plugins/elasticsearch-sql-2.1.0.1.zip/plugin-descriptor.properties: Not a directory thanks

I suspect the problem arose because the location for storing the plugin was incorrect when installing the plugin via the zip file.

If I successfully build it, I’ll share the outcome.

Thank you for your comment!
