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

             Summary: Inconsistent numbers of docs between leader and replica
                 Key: SOLR-7573
                 URL: https://issues.apache.org/jira/browse/SOLR-7573
             Project: Solr
          Issue Type: Bug
    Affects Versions: 4.10.3
            Reporter: Erick Erickson
            Assignee: Erick Erickson


Once again assigning to myself to keep track. And once again not reproducible at will and possible related to firehosing updates to Solr.

Saw a situation where things seemed to be indexed normally, but the number of docs on a leader and follower were not the same. The leader had, as I remember, a 4.5G index and the follower a 1.9G index. No errors in the logs, no recovery initiated, etc. All nodes green.

The very curious thing was that when the follower was bounced, it did a full index replication from the leader. How that could be happening without the follower ever going into a recovery state I have no idea.

Again, if I can get this to reproduce locally I can put more diagnostics into the process and see what I can see. I also have some logs to further explore.
