// Tests mongos's failure tolerance for replica set shards and read preference queries

// Sets up a cluster with three shards, the first shard of which has an unsharded collection and
// half a sharded collection. The second shard has the second half of the sharded collection, and
// the third shard has nothing. Progressively shuts down the primary of each shard to see the
// impact on the cluster.
//
// Three different connection states are tested - active (connection is active through whole
// sequence), idle (connection is connected but not used before a shard change), and new
// (connection connected after shard change).
// Checking UUID and index consistency involves talking to shard primaries, but by the end of this
// test, one shard does not have a primary.
