/**
* Validates multikey compound index in a collection that also contains a hashed index.
* The scenario tested here involves restarting the node after a failed insert due
* to contraints imposed by the hashed index. The validation behavior observed after
* restarting is that, even though we inserted documents that contain arrays in every
* indexed field in the compound index, we fail to save all the multikey path information
* in the catalog.
* @tags: [
* requires_replication,
* requires_persistence,
* ]
