Hi,

unfortunately no, I haven't had the time to reproduce your settings withseparated zookeeper instances.


I'll update if I have something.

Hi,

So this is what I did:----

I created solr as a service. Below are the steps I followed for that:--

$ tar xzf solr-X.Y.Z.tgz solr-X.Y.Z/bin/install_solr_service.sh 
--strip-components=2

$ sudo bash ./install_solr_service.sh solr-X.Y.Z.tgz -i /opt/solr1 -d 
/var/solr1 -u solr -s solr1 -p 8501
$ sudo bash ./install_solr_service.sh solr-X.Y.Z.tgz -i /opt/solr2 -d 
/var/solr2 -u solr -s solr2 -p 8502

Then to start it in cloud I modified the solr1.cmd.in and solr2.cmd.in in 
/etc/defaults/
I added ZK_HOST=192.168.56.103:2181,192.168.56.103:2182,192.168.56.103:2183 
(192.168.56.103 is where my 3 zookeeper instances are)

Then I started the 2 solr services solr1 and solr2

Then I created the configset
/bin/solr zk -upconfig -z 
192.168.56.103:2181,192.168.56.103:2182,192.168.56.103:2183 -n Liferay -d 
server/solr/configsets/sample_techproducts_configs/conf

Then I created the collection using:
http://192.168.56.101:8501/solr/admin/collections?action=CREATE&name=dingdong&numShards=1&replicationFactor=2&collection.configName=liferay
This created fine

Then I deleted the solrconfig.xml from the zookeeper Liferay configset

Then I uploaded the new solrconfig.xml to the configset.

When when I do a reload on the collections I get the error. Or I created a new 
collection I get the error.

Thanks

I have reproduced your steps and the cdcr request handler started successfully. 
I have attached to this mail the config sets I have used.
It is simply the sample_techproducts_config configset with your solrconfig.xml.

I have used solr 6.0.0 with the following commands:

$ ./bin/solr start -cloud

$ ./bin/solr create_collection -c test_cdcr -d cdcr_configs

Connecting to ZooKeeper at localhost:9983 ...
Uploading /solr-6.0.0/server/solr/configsets/cdcr_configs/conf for config 
test_cdcr to ZooKeeper at localhost:9983

Creating new collection 'test_cdcr' using command:
http://localhost:8983/solr/admin/collections?action=CREATE&name=test_cdcr&numShards=1&replicationFactor=1&maxShardsPerNode=1&collection.configName=test_cdcr

{
   "responseHeader":{
     "status":0,
     "QTime":5765},
   "success":{"127.0.1.1:8983_solr":{
       "responseHeader":{
         "status":0,
         "QTime":4426},
       "core":"test_cdcr_shard1_replica1"}}}

$ curl http://localhost:8983/solr/test_cdcr/cdcr?action=STATUS

<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader"><int name="status">0</int><int name="QTime">3</int></lst><lst name="status"><str 
name="process">stopped</str><str name="buffer">enabled</str></lst> </response>



The difference is that I have used the embedded zookeeper, not a separate 
ensemble.

Could you please provide the commands you used to create the collection ?

Kind Regards

I also am using a zk ensemble with 3 nodes on each side.

Hi,

So the way I am doing it is, for both for the Target and Source side, I took a 
copy of the sample_techproducts_config configset, can created one configset. 
Then I modified the solrconfig.xml in there, both for the Target and Source 
side. And then created the collection, and I get the errors. I get the error if 
I create a new collection or try to reload an existing collection after the 
solrconfig update.
Attached is the log and configs.
Thanks

Hi,

I have tried to reproduce the problem, but was unable to.
I have downloaded the Solr 6.0 distribution, added to the solr config the cdcr 
request handler and modified the update handler to register the CdcrUpdateLog, 
then start Solr in cloud mode and created a new collection using my solr 
config. The cdcr request handler starts properly and does not complain about 
the update log.

Could you provide more background on how to reproduce the issue ? E.g., how do 
you create a new collection with the cdcr configuration.
Are you trying to configure CDCR on collections that were created prior to the 
CDCR configuration ?

@Erik: I have noticed a small issue in the CDCR page of the reference guide. In the code 
snippet in Configuration -> Source Configuration, the <updateHandler> element is 
nested within the <requestHandler>.

Thanks
Regards

Erick,

I tried the new configuration. The same issue that Satvinder is
having. The log updater cannot be instantiated...

class="solr.CdcrUpdateLog"

for some reason that class is causing a problem!

Anyway, anyone has a config that works?

Hi,

I had the same problem. The documentation is kind of missleading here.

You

must not add a new <updateHandler> element to your config but
update the existing <updateHandler>. All you need to do is add the
class="solr.CdcrUpdateLog" element to the <updateLog> element
inside your existing <updateHandler>. Hope this helps!
