Minor Description
Last Access Time in the table description is not valid,
Test steps:
Step 1 - create a table
Step 2 - Run command "DESC FORMATTED table"
Last Access Time will always displayed wrong date
Wed Dec 31 15:59:59 PST 1969 - which is wrong.
In hive its displayed as "UNKNOWN" which makes more sense than displaying wrong date.
Please find the snapshot tested in hive for the same com

Seems to be a limitation as of now, better we can follow the hive behavior in this scenario.
