> Currently the error thrown when you cannot acquire a lock is:
> Error in acquireLocks... 
> FAILED: Error in acquiring locks: Locks on the underlying objects cannot be acquired.
retry after some time
> This error is insufficient if the user would like to understand what is blocking them
and insufficient from a diagnosability perspective because it is difficult to know what query
is blocking the lock acquisition.
