-------------------------------------

             Summary: Core mismatch in concurrent documents creation
                 Key: SOLR-4670
                 URL: https://issues.apache.org/jira/browse/SOLR-4670
             Project: Solr
          Issue Type: Bug
          Components: multicore, SolrCloud
    Affects Versions: 4.2, 4.1, 4.0
         Environment: CPU: 32x AMD Opteron(TM) Processor 6276
RAM: 132073620 kB
OS: Red Hat Enterprise Linux Server release 5.7 (Tikanga)

JDK 1.6.0_21
JBoss [EAP] 4.3.0.GA_CP09
Apache Solr 4.x
Apache ZooKeeper 3.4.5

            Reporter: Alberto Ferrini


The issue can be reproduced in this way:
- Install SolrCloud with at least 2 nodes
- Install ZooKeeper with at least 2 nodes
- Create 30 cores
- After each core creation, create 20 random generated documents in a random existent core with 2 concurrent threads on all solr nodes (for example, document 1 in core 3 on node 1, document 2 in core 5 on node 1, document 3 in core 3 on node 2, etc...).
- After all cores creation, query each core for all documents and compare insert data with query result
Some documents result in different core than they are created.
