List and Edit Config Files at Zookeeper from a Client Application

[Furkan KAMACI <fu...@gmail.com>]

Hi;

I am developing an application that will have an ability to list and edit
SolrCloud config files at Zookeeper. Basically operator will able to see
stopwords, synonyms (also elevator). Operator will edit it from my
dashboard and this files will be updated at Zookeper.

Currently I use cloud-scripts that is shipped with Solr. SolrZkClient,
ResourceLoader are options to use. What is the most convenient way for my
list and edit purpose?

Thanks;

Hi;

I've read similar threads and implemented a solution. I think that it maybe
useful for anybody else so I write down what I did:

public class ResourceUpdater {

   public static void updateJsonFileInZk(CloudSolrServer cloudSolrServer,
String zkFilePath, String filePath) throws IOException, KeeperException,
InterruptedException {
      SolrZkClient zkClient = getZkClient(cloudSolrServer);
      File jsonFile = new File(filePath);
      if (!jsonFile.isFile()) {
         System.err.println(jsonFile.getAbsolutePath() + " not found.");
         return;
      }
      byte[] data = readFile(jsonFile);
      updateJsonFileInZk(zkClient, zkFilePath, data);
   }

   public static void updateJsonFileInZk(SolrZkClient zkClient, String
zkFilePath, byte[] jsonData) throws UnsupportedEncodingException,
KeeperException, InterruptedException {
      if (!validateJson(jsonData)){
         System.err.println("Json is invalid");
         return;
      }
      zkClient.setData(zkFilePath, jsonData, true);
   }

   public static void updateJsonFileInZk(CloudSolrServer cloudSolrServer,
String zkFilePath, byte[] jsonData) throws Exception {
      if (!validateJson(jsonData)){
         System.err.println("Json is invalid");
         return;
      }
      SolrZkClient zkClient = getZkClient(cloudSolrServer);
      zkClient.setData(zkFilePath, jsonData, true);
   }

   private static SolrZkClient getZkClient(CloudSolrServer cloudSolrServer){
      ZkStateReader zkStateReader = cloudSolrServer.getZkStateReader();
      return zkStateReader.getZkClient();
   }
}

Thanks;
