I think there's a change in the behavior of SolrCloud vs. what's in the
wiki, but I was hoping someone could confirm for me. I checked JIRA and
there were a couple of issues requesting partial results if one server
comes down, but that doesn't seem to be the issue here. I also checked
CHANGES.txt and don't see anything that seems to apply.
I'm running "Example B: Simple two shard cluster with shard replicas"
from the wiki at https://wiki.apache.org/solr/SolrCloud and everything
starts out as expected. However, when I get to the part about fail over
behavior is when things get a little wonky.
I added data to the shard running on 7475. If I kill 7500, a query to
any of the other servers works fine. But if I kill 7475, rather than
getting zero results on a search to 8983 or 8900, I get a 503 error:
<response>
<lst name="responseHeader">
<int name="status">503</int>
<int name="QTime">5</int>
<lst name="params">
<str name="q">*:*</str>
</lst>
</lst>
<lst name="error">
<str name="msg">no servers hosting shard:</str>
<int name="code">503</int>
</lst>
</response>
I don't see any errors in the consoles.
Also, if I kill 8983, which includes the Zookeeper server, everything
dies, rather than just staying in a steady state; the other servers
continually show:
Nov 03, 2012 11:39:34 AM org.apache.zookeeper.ClientCnxn$SendThread
startConnect
NFO: Opening socket connection to server localhost/0:0:0:0:0:0:0:1:9983
ov 03, 2012 11:39:35 AM org.apache.zookeeper.ClientCnxn$SendThread run
ARNING: Session 0x13ac6cf87890002 for server null, unexpected error,

ov 03, 2012 11:39:35 AM org.apache.zookeeper.ClientCnxn$SendThread
startConnect
over and over again, and a call to any of the servers shows a connection
error to 8983.
This is the current 4.0.0 release, running on Windows 7.
If this is the proper behavior and the wiki needs updating, fine; I just
need to know. Otherwise if anybody has any clues as to what I may be
missing, I'd be grateful. :)
Thanks...
