Re: How to get the creation time of a HTable?

[ShaoFeng Shi]

We have method to identify which tables will not receive read/write
requests; But to be safe, we will exclude the tables that newly created (as
they might be under creating), say in latest 2 days; If Hbase doesn't have
such metadata, it's okay that we add that during the table creation; But if
it can be implemented in the future HBase release, that is good for the
users (especially the admins) I think;

Thanks for the answers and comments!

 After predetermined number of days, would your table(s) not receive any
 read / write requests ?

 Have you considered using TTL for cleaning old data ?

 Cheers

I think we do not have any such attribute for the table but we can implement 
one like we have for Snapshot.

Hm... you can check underlying table catalog on HDFS and see time properties 
there?
