------------------------------------
Summary: Creating a collection with TLOG replicas fails with
placement rules
Key: SOLR-15297
URL: https://issues.apache.org/jira/browse/SOLR-15297
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 7.7.2
Environment: We run on Linux VMs in the google cloud, we see this also
with OnPrem Linux servers as well
Currently using Java 8
Reporter: Webster Homer
When creating a collection with tlog replicas while specifying that a node can
have only 1 replica for a collection, the call fails with the error: TLOG or
PULL replica types not supported with placement rules or cluster policies
We have solr clouds that have 4 nodes and our collections have 2 shards. For
fault tolerance we need to have each replica on a different solr node. but this
is not possible when we need to use TLOG replicas.
Not TLOG collections not supporting placement rules defeats the purpose of
using solrcloud .
This is the call we make:
[http://localhost:8983/solr/admin/collections?action=CREATE&name=b2b-catalog-material-20210320T&collection.configName=b2b-catalog-material-20210320&numShards=2&rule=replica:<2,node:*&tlogReplicas=2|http://localhost:8983/solr/admin/collections?action=CREATE&name=b2b-catalog-material-20210320T&collection.configName=b2b-catalog-material-20210320&numShards=2&rule=replica:%3c2,node:*&tlogReplicas=2]
This was the complete response.
