Hi,
We upgraded our cluster to Solr 4.10.0 for couple days and again reverted back
to 4.8.0. However the dashboard still shows Solr 4.10.0. Do you know why?
* solr-spec 4.10.0
* solr-impl 4.10.0 1620776
* lucene-spec 4.10.0
* lucene-impl 4.10.0 1620776
We recently added new shards to our cluster and dashboard shows correct Solr
version (4.8.0) for these new shards. We copied index from one of old shards
(where it is showing 4.10.0 on dashboard) to this new shard and we see this
error upon start up. How do we get rid of this error?
