Hi Erick, The issue was with zookeeper when we tried to force full replication by cleaning the datadir in zookeeper, caused the index removal.
Our index always replicated full even on short outage or restart. I think "too far out of date" could be the reason. We felt zookeeper was to blame here. We continuously add documents to index on the leader node. Usually we would have 1k - 2k docs more by time time server restarts. We only do softcommits and use commit within call while indexing. Is there a way to change the this "too far out of date" property through solr config? Thanks Shyam On Jan 4, 2013 8:48 PM, "Erick Erickson" <erickerick...@gmail.com> wrote: > > That is very odd.
