Hi Abdel,

Thanks Renaud.

Here is my setup:

1- I have created 2 sites: Main (source) and DR (traget).
2- Both sites are the same before configuring CDCR
3- The collections (source and target) are created before configuring CDCR
4- collections are created using interactive mode: accepting most defaults
except the ports (gettingstarted collection)
5- I have a zookeeper ensemble too.
6- I change the solrconfig.xml, then I upload using the command:
# upload configset to zookeeper
zkcli.bat -cmd upconfig -zkhost  localhost:2181 -confname gettingstarted
-solrhome C:\solr\solr-6-cloud\solr-6.0.0 -confdir
C:\solr\solr-6-cloud\solr-6.0.0\server\solr\configsets\basic_configs\conf

Renaud can you send your confi files...

Thanks,
--Abdel.

Thank you.

To summarize this is what I have, all VMS running on Centos7 :----

Source Side
         |___ 1 VM running 3 Zookeeper instances on port 2181, 2182 and
2183 (ZOOKEEPER 3.4.8)(Java 1.8.0_91)

6.0) (Java 1.8.0_91)
         |___ sample_techproducts_config copied as 'liferay', and used to
create collections, that is where I am
  modifying the solrconfig.xml


Target Side
         |___ 1 VM running 3 Zookeeper instances on port 2181, 2182 and
2183 (ZOOKEEPER 3.4.8)(Java 1.8.0_91)

Thanks Satvinder,
Tomorrow, I'll try to reproduce the issue with your steps and will let you
know.

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?

I changed the CDCR doc, Oliver could you take a glance and see if it
is clear now? All I changed was the sample solrconfig sections....

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!
