Subject Error getting replica locations : unable to get autoscaling policy session when creating collection
Date Sat, 02 Feb 2019 05:49:02 GMT
Hi,

I am using Solr 7.6.0.

When I tried to create a collection, I encountered the error of unable to
get autoscaling policy session.

I have 2 replicas running, and I am creating it with the following command:
https://localhost:8983/solr/admin/collections?action=CREATE&name=collection1&numShards=1&replicationFactor=2&maxShardsPerNode=2&collection.configName=collection1

What could be the reason that caused this error?

This is the error which I am getting:
