Subject Re: Error when creating collection

Looking on the logs of the other server, I see this:

SEVERE: org.apache.solr.common.SolrException: I was asked to wait on state recovering for
192.168.1.155:8983_solr but I still do not see the requested state. I see state: active live:true

Shawn,

I set a shard ID however am still getting the same issue. The logs on the solr server are
reporting the following:

The request is being performed on 192.168.1.155 and it is timing out when contacting another
server in the zookeeper group (192.168.1.152). There are no firewall rules in place and I
am able to lynx from 192.168.1.155 to 192.168.1.152 on that port.

SEVERE: Error while trying to recover. core=collection1:org.apache.solr.client.solrj.SolrServerException:
Timeout occured while waiting response from server at: http://192.168.1.152:8983/solr
        at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:412)
        at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:181)
        at org.apache.solr.cloud.RecoveryStrategy.sendPrepRecoveryCmd(RecoveryStrategy.java:202)
        at org.apache.solr.cloud.RecoveryStrategy.doRecovery(RecoveryStrategy.java:346)
        at org.apache.solr.cloud.RecoveryStrategy.run(RecoveryStrategy.java:223)
Caused by: java.net.SocketTimeoutException: Read timed out

Thanks,
Mark

This is happening because you never set the shard ID.  See the "Caused
by" message above.  There is a setShardID method on the class that you
are using.  I believe this would typically get something like "shard1"
as a value.

The user that runs Solr must typically have write permissions to the
solr home and all of its descendants.

Note that with the CoreAdminRequest class, you are not creating a
collection.  You are creating a core.  If you want to create an entire
collection (which will typically create at least two cores on different
Solr instances), you need to use CollectionAdminRequest instead.
