Subject [jira] [Commented] (SOLR-4114) Collection API: Allow multiple shards from one collection on the same Solr server
Date Fri, 28 Dec 2012 08:06:13 GMT

    [ https://issues.apache.org/jira/browse/SOLR-4114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13540383#comment-13540383
] 

Per Steffensen commented on SOLR-4114:
--------------------------------------

Maybe you ought to fix the real problem instaed - making Solr behave equally whether it is
checked out from GitHub or SVN.

Had a look at your fix - it ought to be
{code}
&& ((value = server.getAttribute(mbean, "coreName")) != null)
{code}
instead of
{code}
&& ((indexDir = server.getAttribute(mbean, "coreName")) != null)
{code}

> We should support running multiple shards from one collection on the same Solr server
- the run a collection with 8 shards on a 4 Solr server cluster (each Solr server running
2 shards).
> Performance tests at our side has shown that this is a good idea, and it is also a good
idea for easy elasticity later on - it is much easier to move an entire existing shards from
one Solr server to another one that just joined the cluter than it is to split an exsiting
shard among the Solr that used to run it and the new Solr.

server"
