Description

I am using solr cloud 4.3.1 with zookeeper for coordination

We shard our data (mostly 2-3 shards) with a replication factor of 2. After I make changes to schema/configs and upload to zookeeper, I reload the collection that was updated (to use the latest schema)

This call reloads all the shards but for some reason, a few of the shards are "marked as down" by zookeeper. However the shards are healthy and are queryable

It seems many of them are experiencing this issues with solr cloud (Googling around forums/stack overflow tells me this)

Is this a known issue? If not what would be a recommended fix?

Thanks a ton
