How to Learn Linked Configuration for SolrCloud at Zookeeper

Hi;

I've written a code that I can update a file to Zookeeper for SlorCloud.
Currently I have many configurations at Zookeeper for SolrCloud. I want to
update synonyms.txt file so I should know the currently linked
configuration (I will update the synonyms.txt file under appropriate
configuration folder) How can I learn it?

Thanks;
Furkan KAMACI

Hi;

OK, I've checked the source code and implemented that:

   public String readConfigName(SolrZkClient zkClient, String collection)
throws KeeperException, InterruptedException {

      String configName = null;

      String path = ZkStateReader.COLLECTIONS_ZKNODE + "/" + collection;

      LOGGER.info("Load collection config from:" + path);
      byte[] data = zkClient.getData(path, null, null, true);

      if (data != null) {
         ZkNodeProps props = ZkNodeProps.load(data);
         configName = props.getStr(CONFIGNAME_PROP);
      }

      if (configName != null && !zkClient.exists(CONFIGS_ZKNODE + "/" +
configName, true)) {
         LOGGER.error("Specified config does not exist in ZooKeeper:" +
configName);
         throw new ZooKeeperException(SolrException.ErrorCode.SERVER_ERROR,
"Specified config does not exist in ZooKeeper:" + configName);
      }
      return configName;
   }

So, I can get the linked configuration name.

Thanks;

I am looking it for a particular collection.

For a particular collection or core?  There should be a collection.configName property specified for the core or collection which tells you which ZK config directory is being used.
