cleanupOrphaned doesn't verify startingFromKey matches shard key spec

var st = new ShardingTest({ other: { rs: true, rsOptions: {nodes: 2} } });   var mongos = st.s0; var coll = mongos.getCollection('foo.bar'); var shardAdmin = st.shard0.getDB('admin');   mongosAdmin.runCommand({ enableSharding: coll.getDB().getName() });   mongosAdmin.runCommand({ shardCollection: coll.getFullName(), key: {_id: 1} });   // Doesn't match number of keys. assert.commandFailed(shardAdmin.runCommand({ cleanupOrphaned: coll.getFullName(), startingFromKey: {someKey: 'someValue', someOtherKey: 1} }));   // Matches number of keys but not key name. This will succeed but should fail. assert.commandFailed(shardAdmin.runCommand({ cleanupOrphaned: coll.getFullName(), startingFromKey: {someKey: 'someValue'} }));
