             Summary: Have an option to disable autoAddReplicas temporarily for all collections
                 Key: SOLR-6879
                 URL: https://issues.apache.org/jira/browse/SOLR-6879
             Project: Solr
          Issue Type: Improvement
            Reporter: Varun Thacker


When doing offline maintenance on my cluster I would like to disable autoAddReplicas since I don't want replicas being created on nodes during this time.

It would be useful to have an option to enable/disable autoAddReplicas via an API.

This API would disable autoAddReplicas:
{code}
admin/collections?action=CLUSTERPROP&name=autoAddReplicas&val=false
{code}

Now when I want to enable it again the API call would look like this:

{code}
admin/collections?action=CLUSTERPROP&name=autoAddReplicas
{code}

This uses the CLUSTERPROP semantics of unsetting a property when the {{val}} param is not provided.
