[jira] [Updated] (SOLR-4260) Inconsistent numDocs between leader and replica

     [ https://issues.apache.org/jira/browse/SOLR-4260?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Markus Jelsma updated SOLR-4260:
--------------------------------

    Component/s:     (was: update)
                 SolrCloud
        Summary: Inconsistent numDocs between leader and replica  (was: Inconsistent docFreq and docCount before and after forceMerge/optimize)

Of course, you're right! I got distracted by that fact and in the process renamed this issue while i shouldn't. The inconsistency between leader and replica on one shard is still here.

I'll rename it back and raise the docFreq and docCount issue on the list. Sorry for the mess :)

> After wiping all cores and reindexing some 3.3 million docs from Nutch using CloudSolrServer we see inconsistencies between the leader and replica for some shards.
> Each core hold about 3.3k documents. For some reason 5 out of 10 shards have a small deviation in then number of documents. The leader and slave deviate for roughly 10-20 documents, not more.
> Results hopping ranks in the result set for identical queries got my attention, there were small IDF differences for exactly the same record causing a record to shift positions in the result set. During those tests no records were indexed. Consecutive catch all queries also return different number of numDocs.
> We're running a 10 node test cluster with 10 shards and a replication factor of two and frequently reindex using a fresh build from trunk. I've not seen this issue for quite some time until a few days ago.
