> Currently OperationManager is designed to hold all the operations from all
> the sessions. It will cause the functions to unnecessarily sync between the
> operations across the sessions. And also there are some functions are not
> threadsafe which could be the cause for invalid OperationHandle.
> Plan to change OperationManager to just serve one session and make it a
> helper class for HiveSession rather than a service which doesn't seem to be
> needed.
