I wanted to run a solr cloud with solr 4.3.0.
(I am using aws ubuntu-12.04-lts micro instances)
So I followed this toturial:
which basically says, start the zookeeper and connect the solr instances to it.
Here's how I start the zookeeper.
First I copied the config like described in the tutorial
sudo cp zookeeper-3.4.5/conf/zoo_sample.cfg zookeeper-3.4.5/conf/zoo.cfg
Then I started the zookeeper
ubuntu#ip-10-48-159-36:/opt$ sudo zookeeper-3.4.5/bin/zkServer.sh start
JMX enabled by default
Using config: /opt/zookeeper-3.4.5/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
Looks fine so far.
I checked the status:
ubuntu#ip-10-48-159-36:/opt$ sudo zookeeper-3.4.5/bin/zkServer.sh status
JMX enabled by default
Using config: /opt/zookeeper-3.4.5/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.
Which seems a bit weird already.
If I try to connect with the client (remote as well as local), its seems to work
ubuntu#ip-10-234-223-69:/opt$ zookeeper-3.4.5/bin/zkCli.sh -server ec2-54-247-144-120.eu-west-1.compute.amazonaws.com:2181

What does it tell me?
On the same instance I just connected with the client successfully... :(
So where is the problem?
[Edit:]
Instead of using amazons ec**.amazon.* address I used the network addresses 10.X.X.X for telling solr where the zookeeper is.
It seems to work.
You have your answer - Your ZooKeeper in inaccessible!
Check your firewall configuration.
You can also check it with
zkCli.sh -server localhost:2181
There must have been some sort of connectivity problem.
I see you have it resolved now.
Next time you run into a situation like this, you should log onto the box that is having problems connecting and use telnet to see if you can connect.
eg: from your solr box:
telnet ec2-54-247-144-120.eu-west-1.compute.amazonaws.com 2181
and then try from the zk box too. It should start to illuminate where your issues are.
That eliminates any application layer issues and will tell you quite reliably wether or not you can connect. It you can't connect, then it's almost always some sort of security issue - either a firewall running somewhere (try - $service iptables stop) or it will be an issue with security group configuration in amazon.
The last potential problem is network availability. Despite what people think, the network is NOT reliable and should never be considered so. Anyone working in SOA/distributed systems will know this well :)
http://aphyr.com/posts/288-the-network-is-reliable
"A team from the University of Toronto and Microsoft Research studied the behavior of network failures in several of Microsoft’s datacenters. They found an average failure rate of 5.2 devices per day and 40.8 links per day with a median time to repair of approximately five minutes (and up to one week). "
While setting up SolrCloud and ZooKeeper I also ran into the "Error contacting service. It is probably not running." issue. The reason was a typo in a file name that ZooKeeper needs. The correct file name is "myid". I wrote "myip" by mistake. After the renaming of the file and restarting ZooKeeper (./zkServer.sh restart), my issue was resolved.
try to stop your solr instance solr.shutdown() so that you can create new CloudSolrServer instance for each thread

Now, I want to change application to point to my dev db box:

But, I am getting following error:

at com.microsoft.sqlserver.jdbc.SQLServerException.ConvertConnectExceptionToSQLServerException(SQLServerException.java:285)
Clearly, I can get to the database.
Does anyone know what i am doing wrong?
The JDBC Url should look like:
jdbc:sqlserver://[serverName[\instanceName][:portNumber]][;property=value[;property=value]]
Building the Connection URL
And the error makes it clear that you are not connecting on port 28001:
connection to the host JD1LSTWLSLMC101.dcsr.site,28001, port 1433 has
failed
So
spring.datasource.url=jdbc:sqlserver://JD1LSTWLSLMC101.dcsr.site:28001; . . .
I have a SolrCloud cluster (6.6) setup with external Zookeeper Ensemble (3.4.8) of 5 nodes. Recently, one machine (ip1:port1) that run 1 Zookeeper with id=1 went down. This is what I've done to replace zookeeper:
Start zookeeper in another machine with the same id (=1).
Change zoo.cfg in 4 live zookeeper to match new zookeeper server and restart.
Update ZK_HOST variable in solr.in.sh to match new zookeeper server.
Restart solr.
After that, my solr cluster seemed to functioning well, but in solr.log, it looked like solr client and zookeeper servers still try to connect to the old zookeeper:

I've done some search in add/remove zookeeper but didn't find a document for it. My zookeeper version (3.4.7) is not supported for dynamic reconfiguration (which is in zookeeper 3.5).
Is there a way I can manually remove/add zookeeper server from ensemble?
Thanks for your attention!

zoo.cfg as bellow
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/lib/zookeeper
clientPort=2181
server.1=localhost:2888:3888
server.2=<My ec2 private IPs>:2889:3889
also I have created myId file as on both ec2 instances - /var/lib/zookeeper/myid
I also tried to edit /ect/hosts file but still facing the same issue.
also how I can start both of the zookeeper instances by 1 command?
Note: Server get started successfully if I tried with bin/zkCli.sh start command.
Thanks in advance!
look zk log zookeeper.out，if there have connection limit error, configure the following to zoo.cfg.
# the maximum number of client connections.
# increase this if you need to handle more clients
maxClientCnxns=60
This is temporary error , for mine after some time , It gone away :-
This is my zoo.conf file ::-
Dir=../data
clientPort=2181
tickTime=2000
initLimit=5
This error occurred when I forgot to run% ZOOKEEPER_HOME% \ bin \ zkserver.cmd
By running, the problem has been resolved.
Correct this property on the server.properties
default would be localhost change it to match the zookeeper server starup ip and port
zookeeper.connect=0.0.0.0:2181
We try to import our data into SolrCloud using MapReduce batch indexing. We face a problem at the reduce phase, that solr.xml cannot be found. We create a 'twitter' collection but looking at the logs, after it failed to load in solr.xml, it uses the default one and tries to create 'collection1' (failed) and 'core1' (success) SolrCore. I'm not sure if we need to create our own solr.xml and where to put it (we try to put it at several places but it seems not to load in). Below is the log:

solr looks for solr.home parameter and searchs solrConfig.xml file there. if there is none it tries to load default configuration.
it looks like your solr home is
/data/06/mapred/local/taskTracker/distcache/3866561797898787678_-1754062477_512745567/master.hadoop/tmp/9501daf9-5011-4665-bae3-d5af1c8bcd62.solr.zip/collection1/
check that folder for solrconfig.xml file
if there is none, copy one from example directory of solr
if there is one, match the file/folder permissions with the server instance
