> If there are a large number of tables in the HBase cluster, it will take a long time to fully load the table descriptor  from filesystem for the first time.
> In our production cluster, there were 50000 + tables. It took several minutes to load the table descriptor from filesystem. This problem seriously affects the performance of HMaster active/standby switchover.
> We should support concurrent loading to solve this problem.
