Jens Bo Rasmussen updated SOLR-3418:
------------------------------------
Summary: Sometimes data is not replicated to replica slices which are added
to a SolrCloud cluster which runs without replica (was: Sometimes data is not
replicated to replica slices added to a SolrCloud cluster which are running
without replica)

> Key: SOLR-3418
> URL: https://issues.apache.org/jira/browse/SOLR-3418
> Project: Solr
> Issue Type: Bug
> Components: replication (java)
> Affects Versions: 4.0
> Environment: Linux 2.6.32-29-server #58-Ubuntu SMP Fri Feb 11
> 21:06:51 UTC 2011 x86_64 GNU/Linux, Solr snapshot from 29th of February 2012,
> 2 Solr machines with 1 slice each and 0 replica
> Reporter: Jens Bo Rasmussen
> Priority: Minor
> Labels: replica
> Fix For: 4.1
>
> Original Estimate: 120h
> Remaining Estimate: 120h
>
> Scenario: ensure that replica slices specified in the configuration are added
> on sequential node restart without loosing data
> Given a SolrCloud cluster is running with
> number of servers (Solr nodes): 2
> number of slices per node: 1
> number of replica per slice: 0
> number of documents in leader slice on first Solr node: 4
> number of documents in leader slice on second Solr node: 1
> When I configure each node with 1 replica per slice
> And I restart the nodes one at a time
> Then I would expect that the SolrCloud cluster is running with
> number of servers (Solr nodes): 2
> number of slices per node: 1
> number of replica per slice: 1
> number of documents in leader slice on first Solr node: 4
> number of documents in replica slice on second Solr node: 4
> number of documents in leader slice on first Solr node: 1
> number of documents in replica slice on second Solr node: 1
> Testresult: the scenario has been performed several times with success
> however sometimes data is not replicated; it has been observed that sometimes
> no data is replicated at all and sometimes only data from one of the slices
> is replicated
