> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: replication (java), Schema and Analysis, SolrCloud,
> update
> Affects Versions: 7.1
> Environment: Linux version 2.6.32-642.15.1.el6.x86_64
> (mockbu...@c1bm.rdu2.centos.org) (gcc version 4.4.7 20120313 (Red Hat

> An operating SolrCloud with NRT, TLOG, and PULL replicas.
> Solr - 7.1.0
> ZK - 3.4.10
> Used config set - sample_techproducts_configs
> Shards - 1
> Whenever a schema change (adding of new fields/changing field types) is
> pushed to ZK and the collection is reloaded using
> /solr/admin/collections?action=RELOAD&name=sample, the index changes stop
> replicating to PULL replicas. NRT and TLOG are able to replicate the index.
> Before the schema change, I can see the indexFetcher thread running on PULL
> replica

> I can no longer see IndexFetcher thread running on PULL replica. No logs are

> The index is never modified after this, and leader doesn't get the polls from
> the PULL replica.
> Observations:
> - Manually forcing an index fetch using /replication?command=fetchindex syncs
> the index, but doesn't start the IndexFetcher polling.
> - Restarting the replica will sync the index, starts IndexFetcher thread and
> polling.
> - Removing and adding the replica back as PULL will sync the index, starts
> IndexFetcher thread and polling.
