Erick Erickson created SOLR-7716:
------------------------------------
Summary: misleading errors reported for CREATESHARD if new shard
would exceed maxShardsPerNode
Key: SOLR-7716
URL: https://issues.apache.org/jira/browse/SOLR-7716
Project: Solr
Issue Type: Improvement
Components: SolrCloud
Affects Versions: 5x, Trunk
Reporter: Erick Erickson
Priority: Minor
If I create a collection with implicit routing and, say, maxShardsPerNode=3,
then start creating shards, when I create the 4th shard I get an error. So far
so good. The error is very misleading though, see below.
Saw this on a degenerate case of a single Solr instance, not sure if you get
the same error on a multi-node cluster.
<str name="Operation createshard caused exception:">
...... Cannot create collection eoe. No live Solr-instances
</str>
<lst name="exception">
<str name="msg">Cannot create collection eoe. No live Solr-instances</str>
<int name="rspCode">400</int>
.
.
.
Related question is I don't think there's a graceful way to increase
maxShardsPerNode after the collection is created.
