Jason Venner (at ning) updated SOLR-1395:
-----------------------------------------
Attachment: katta.zk.properties
katta.node.properties
solr-1395-1431-3.patch
/tmp/solr-1395-1431-3.patch contains an additional unit test for the query
string serialization code, and two additional classes that allow for deployment
to katta.
WIth this jar, a katta client node may be started via
katta-daemon.sh start katta\ startNode
org.apache.solr.katta.DeployableSolrKattaServer
The system properties that control the node startup are
solr.server.name - the property to look for the server name, default proxy
solr.home - the property to look for the server root, default solrHome
solr.config.file - the property to look for the server config file name,
default solr.xml
These will be used to find a solr configuration to run the embedded server
which will search the deployed shards.
Index shards may be deployed via the standard katta mechanism of katta addIndex
index-name shared-path-to-index
I use the zip files produced by SOLR-1301 and deploy from hdfs.
For searching, create a solr configuration with a handler:
<requestHandler name="standard" class="solr.KattaRequestHandler"
default="true">
<!-- default values for query parameters -->
<lst name="defaults">
<str name="echoParams">explicit</str>
<!--
<int name="rows">10</int>
<str name="fl">*</str>
<str name="version">2.1</str>
-->
<str name="shards">*</str>
</lst>
</requestHandler>
This will search all deployed shards, replace the shards parameter with an
explicit shard list if you only wish to query an explicit subset with this
query handler.
The solr instance for search will need the zookeeper information.
conf/katta.node.properties
conf/katta.zk.properties, replace the zookeeper nodes with your clusters nodes
I tend to run java -d64 -Xmx2g -Dkatta.request.timeout=100000 start.jar
for my testing work as my cluster is on the far side of a couple of firewals
