Re: List and Edit Config Files at Zookeeper from a Client Application

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;
