// SERVER-16498 d_migrate.cpp should not rely on system.namespaces

// This test creates a sharded collection with wiredtiger options.
|
|
// When the chunks of this collection get migrated to the other shard,
|
|
// the other shard should create the collection with the same options.
|
|
// However, before SERVER-16498, the receiver relies on checking
|
|
// system.namespaces on the donor, which is empty on wiredtiger.
|
|
// As a result, the new collection created on receiver has different
|
|
// options.
|
|

|
|
// P.S. wiredtiger options are not valid for MMAPv1, but MMAPv1 will
|
|
// keep and ignore them.
