Re: Using Zookeeper with REST URL
Look at the \contrib\rest directory for zookeeper-3.4.5-rest.jar.

Re: issue in launching SolrCloud windows/cygwin
Run Solr straight from the Windows cmd if CygWin isn't a requirement. For example, running java -jar start.jar from the example directory will start single instance Solr. To run SolrCloud follow the instructions in Simple Two-Shard Cluster on the Same Machine from this link http://bit.ly/1rlmYvF . @nazik_huq On Sun, Oct 19, 2014 at 2:51 AM, Anurag Sharma anura...@gmail.com wrote: Here is the issue am facing issue in using the 'solr' script on Windows with cygwin terminal: $ bin/solr -e cloud bin/solr: line 16: $'\r': command not found bin/solr: line 17: $'\r': command not found bin/solr: line 46: $'\r': command not found which: no lsof in (/usr/local/bin:/usr/bin:/cygdrive/c/Windows/system32:/cygdrive/c/Windows:/cygdrive/c/Windows/System32/Wbem:/cygdrive/c/Windows/System32/WindowsPowerShell/v1.0:/cygdrive/c/Program Files/TortoiseSVN/bin:/cygdrive/c/Program Files/Java/jdk1.7.0_51/bin:/cygdrive/c/Program Files/apache-ant-1.9.3/bin:/cygdrive/c/Program Files (x86)/Python-27:/cygdrive/c/Program Files (x86)/Python-27/Scripts) bin/solr: line 52: $'\r': command not found bin/solr: line 87: syntax error near unexpected token `$HOME/.solr.in.sh ' 'in/solr: line 87: ` $HOME/.solr.in.sh \ further $ bin/solr start -cloud -d node1 -p 8983 bin/solr: line 16: $'\r': command not found bin/solr: line 17: $'\r': command not found bin/solr: line 46: $'\r': command not found which: no lsof in (/usr/local/bin:/usr/bin:/cygdrive/c/Windows/system32:/cygdrive/c/Windows:/cygdrive/c/Windows/System32/Wbem:/cygdrive/c/Windows/System32/WindowsPowerShell/v1.0:/cygdrive/c/Program Files/TortoiseSVN/bin:/cygdrive/c/Program Files/Java/jdk1.7.0_51/bin:/cygdrive/c/Program Files/apache-ant-1.9.3/bin:/cygdrive/c/Program Files (x86)/Python-27:/cygdrive/c/Program Files (x86)/Python-27/Scripts) bin/solr: line 52: $'\r': command not found bin/solr: line 87: syntax error near unexpected token `$HOME/.solr.in.sh ' 'in/solr: line 87: ` $HOME/.solr.in.sh \ Is there any other way I can run the SolrCloud using java -jar start.jar options?

Re: Asp.net MVC 4 and Solr Query Begining
Hi Daniel,
I think you should post this to SOLR.NET google group:
https://groups.google.com/forum/m/#!forum/solrnet
That forum is more appropriate to address this type of problem.

Hello to all, I am new in Solr, but I see it si very usable. So I whant to
build web application with asp.net MVC 4 that shows query from Solr.
Ok, let's go so far i have done this:
1) Open new project in Visual Studio 2012 and create new MVC 4 project
(Empty solution).
2) In Package Manager Console I have Install next packages:
/SolrNet (core library)
SolrNet.Windsor
SolrNet.StructureMap
SolrNet.Ninject
SolrNet.Unity
SolrNet.Autofac
SolrNet.NHibernate/
3) I create new Model class with name Poskus and write this code:
using SolrNet.Attributes;
/namespace TestSolr2.Models
{
public class Poskus
{
[SolrField(customer)]
public string Customer { get; set; }
}
}/
4) Next I have create new Controller with name PoskusSolr and write this
code:
/using System;
using System.Web.Mvc;
using SolrNet;
using SolrNet.DSL;
using TestSolr.Models;
using SolrNet.Impl;
namespace TestSolr.Controllers
{
public class PoskusSolrController : Controller
{
//
// GET: /PoskusSolr/
public ActionResult Index()
{
try
{
var connection = new
SolrConnection(http://servicemix/.../msglog_pilot;);
Startup.InitPoskus(connection);
var pos1 = Solr.QueryPoskus(new SolrQueryByField(name,
customer));
return View(pos1);
}
catch (Exception ex)
{
string error = ex.Message;
}
return View();
}
}
}/
5) And finaly I have create View (Index)
So far I put this:
/@model TestSolr.Models.Poskus
@{
ViewBag.Title = Index;
}
Index
/
-
Now, this code does not work, it not returns customers from my Solr databse.
Any sugestions, ideas, links to make this work. Realy, realy thanks for
help.
Daniel

SolrCloud recovery after nodes are rebooted in rapid succession
Hello, I have a question from a colleague who's managing a 3-node(VMs) SolrCloud cluster with a separate 3-node Zookeeper ensemble. Periodically the data center underneath the SolrCloud decides to upgrade the SolrCloud instance infrastructure in a rolling upgrade fashion. So after the 1st instance of the SolrCloud is shut down and while it is in the process of rebooting, the 2nd instance starts to shut down and so on. Eventually all three Solr instances are rebooted and up and running but the cluster in now inoperable. Meaning clients can't query or ingest data. My colleague is trying to ascertain if this problem is due to Solr's inability to recover from a rapid succession of reboots of the nodes or from the data center upgrade that is triggering a situation making SolrCloud inoperable. My question is, can a SolrCloud cluster become inoperable after its nodes are rebooted in rapid succession as described above? Is there an edge case similar to this? Thanks, Nazik Huq

Re: Zookeeper as Service
From your email I gather your main concern is starting zookeeper on server startups. You may want to look at these non-native service oriented options too: Create a script( cmd or bat) to start ZK on server bootup. This method may not restart Zk if Zk crashes(not the server). Create C# commad line program that starts on server bootup(see above) that uses the .Net System.Diagnostics.Process.Start method to start Zk on sever start and monitor the Zk process via a loop. Restart when Zk process crash or hang. I prefer this method. There might be a Java equivalent of this. There are many exmaples avaialble on the web.

There are various ways to 'servicify' (yes that may not be an actual word) executable applications on Windows. The venerable SrvAny is one such option as is the newer nssm.exe (Non-Sucking Service Manager). Bear in mind that a Windows Service doesn't operate quite the same way with regard to stdout and stderr which may mean any error messages end up in a black hole, with you simply getting something unhelpful 'service failed to start' error messages from Windows itself if something goes wrong. The 'working directory' is another thing that needs careful setting up.
