// Validates cases where index scans are aborted due to the collection being dropped (SERVER-4400)
|
|
//
|
|
// Drop and other sharding commands can conflict with LockBusy errors in a sharding passthrough
|
|
// suite. This is because drop against a mongos takes distlocks, whereas drop against a mongod does
|
|
// not. Due to the huge number of parallel drops in this test, the other thead is very likely to be
|
|
// starved frequently.
|
|
// Note: this tag can be safely removed once PM-697 is complete and replaces distlocks with a
|
|
// LockManager that has a fairness policy, which distlocks lack.
|
|
// @tags: [
|

// assumes_against_mongod_not_mongos,
