Alicia Ying Shu commented on PHOENIX-1409:
------------------------------------------
Patch v3 failed on the following TTL case:
create table T (col1 varchar primary key);
alter table T set TTL = 30;
It did not set the TTL to be 30 since existingColumnFamilies.isEmpty() when
there is only default column family. I added the following code to fix it
(there could be other way to get the existing column family including default
one):
if (existingColumnFamilies.isEmpty() && newColumnFamiliesToBeAdded.isEmpty() &&
!commonFamilyProps.isEmpty()) {
allFamiliesProps.put(QueryConstants.DEFAULT_COLUMN_FAMILY, commonFamilyProps);
}
Patch v4 passed all the mvn tests. Will modify some more as suggested.

> 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.
