James Taylor commented on PHOENIX-1409:
---------------------------------------
Does HBase support a TTL for the table as well as for a column family? What
happens if they're set to different values?
If it's only per column family, then ALTER TABLE set_ttl_test SET TTL=100
should set the TTL to 100 for the default column family only IMO (I believe
that's the logic that's in place now in general - would you mind confirming how
it works when you set TTL in CREATE TABLE statement when there's more than one
column family?). If the user wants to set it for all column families, then
they'd need to list them out like this: ALTER TABLE set_ttl_test SET a.TTL=100,
b.TTL=100.
> Allow ALTER TABLE <table> SET command to update HTableDescriptor and
> HColumnDescriptor properties

> Once PHOENIX-1408 is fixed, we should allow HTableDescriptor and
> HColumnDescriptor properties through the ALTER TABLE <table> SET command.
> It'd just be a matter of passing these properties through the existing
> methods, as we support this for CREATE TABLE.
