Subject Re: cdcr replication only 1 node gets data
Date Tue, 04 Jul 2017 22:06:22 GMT
We too often end up with a shard looking like:
"name": "shard2",
"range": "0-7fffffff",
"state": "active",
"replicas": [

"name": "core_node1",
"core": "sial-catalog-gene_shard2_replica2",
"baseUrl": "http://uc1f-ecom-msc01:8983/solr",
"nodeName": "uc1f-ecom-msc01:8983_solr",
"state": "active",
"leader": true,
"numDocs": 57376,
"maxDocs": 86447,
