Hi Artem,
This question (or one very like it) has been asked on this list before so
there's some prior art you could modify to suit your needs.
Taken from Timothy Potter <thelabd...@gmail.com>:
**
public static void updateClusterstateJsonInZk(CloudSolrServer
cloudSolrServer, CommandLine cli) throws Exception {
String updateClusterstateJson =
cli.getOptionValue("updateClusterstateJson");
ZkStateReader zkStateReader = cloudSolrServer.getZkStateReader();
SolrZkClient zkClient = zkStateReader.getZkClient();
File jsonFile = new File(updateClusterstateJson);
if (!jsonFile.isFile()) {
System.err.println(jsonFile.getAbsolutePath()+" not found.");
return;
}
byte[] clusterstateJson = readFile(jsonFile);
// validate the user is passing is valid JSON
InputStreamReader bytesReader = new InputStreamReader(new
ByteArrayInputStream(clusterstateJson), "UTF-8");
JSONParser parser = new JSONParser(bytesReader);
parser.toString();
zkClient.setData("/clusterstate.json", clusterstateJson, true);
System.out.println("Updated /clusterstate.json with data from
"+jsonFile.getAbsolutePath());
}
**
You should be able to modify that or use it as a basis for uploading the
changed files in your config.
Thanks,
Greg
