Hi Erick, First of all, thank you very much for answering i really
appreciate it, i've being reading alot of articles (some by you) in the
past 2 weeks.
Its very confusing the replication process and i didnt find articles about
this, The main differences in solrcloud 5. From what I thought, by stating
a <ReplicationHandler> in solrconfig, i can over-ride the existing
solrcloud ReplicationHandler behavior, I have not stated any
ReplicationHandler node in my config yet.
How do you know solr is using the old replication style ? What i did wrong
in configuration ?
I Downloaded 5.2.1 package, and followed a simple guide, I dont declare the
master/slave anywhere, it is all done automaitcally (and happening just
fine). I am using the basic config set that is supplised with solr
installation, Then I added my custom update request handler and changed the
schema.
*Important:*
Today I saw in Basic config set (provided in installation) they use
distributed update processor as you mentioned, So in my custom update
request handler, I have added <processor
class="solr.RunUpdateProcessorFactory" /> just before
RunUpdateProcessorFactory, But it throw exception that i have 2
DistributedUpdateProcessorFactory in WitStandardUpdater
How could that be ??
