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

             Summary: Deleting the data directory on master and reindexing causes slaves to out of sync
                 Key: SOLR-4350
                 URL: https://issues.apache.org/jira/browse/SOLR-4350
             Project: Solr
          Issue Type: Bug
          Components: replication (java)
    Affects Versions: 4.1
         Environment: Windows
            Reporter: Senthuran Sivananthan
            Priority: Minor


This issue occurs only when the data directory is deleted manually on the master instance.

Here are the steps that I used to replicate the issue:

Master - Shutdown
Master - Delete Data Directory
Slave - Replication triggers, but no connection to master, replicaiton fails
Master - Start Up
Master - Index all docs
Master - Shutdown
Master - Start Up

Expected: Slave - Replication triggers, connected to master, new index replications, master & slave in sync

Actual:  Slave - Replication triggers, connected to master, error seen in the logs: "SEVERE: No files to download for index generation: 2"

  * Nothing will replicate even if master generation > slave generation

Workaround:

  * Must trigger another commit on master after the restart
	* Replicates even if master generation < slave generation (and gets the generations in sync)

	* Replicates when master generation > slave generation
