David Smiley updated SOLR-3420:
-------------------------------
Fix Version/s: (was: 4.7)
4.8
> Data is not replicated from replica slices to leader slices
> -----------------------------------------------------------
>
> Key: SOLR-3420
> URL: https://issues.apache.org/jira/browse/SOLR-3420
> Project: Solr
> Issue Type: Bug
> Components: replication (java)
> Affects Versions: 4.0-ALPHA
> 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 1 replica
> Reporter: Jens Bo Rasmussen
> Labels: replica
> Fix For: 4.8
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Scenario: ensure that data is not lost when leader slices and replica slices switch roles due to an untimely restart of both nodes
> Given a SolrCloud cluster is running with
> number of nodes: 2
> number of slices per node: 1
> number of documents in leader slice1_shard1 on first Solr node: 1
> number of documents in replica slice2_shard1 on second Solr node: 1
> number of documents in leader slice2_shard2 on first Solr node: 1
> number of documents in replica slice1_shard2 on second Solr node: 1
> And the second node is stopped
> And x new documents are added to each slice on the first node
> And the first node is stopped
> When the second node is started and the slices become leader slices
> And the first node is started and the slices become replica slices
> Then I would expect that the SolrCloud cluster is running with
> number of nodes: 2
> number of slices per node: 1
> number of documents in replica slice1_shard1 on first Solr node: 1+x
> number of documents in leader slice2_shard1 on second Solr node: 1+x
> number of documents in replica slice2_shard2 on first Solr node: 1+x
> number of documents in leader slice1_shard2 on second Solr node: 1+x
> Testresult: data is not replicated
> number of servers (Solr nodes): 2
> number of slices per node: 1
> number of replica per slice: 1
> number of documents in replica slice1_shard1 on first Solr node: 1+x
> number of documents in leader slice2_shard1 on second Solr node: 1
> number of documents in replica slice2_shard2 on first Solr node: 1+x
> number of documents in leader slice1_shard2 on second Solr node: 1
> ==> data is not replicated from replica slices to leader slices
