VERSIONS and TTL mutually exclusive?

I'm using HBase 0.20.6.

For column definitions are VERSIONS and TTL mutually exclusive?

For example, what happens if I define a column like so:

create "pages", {NAME => 'info', COMPRESSION=>'gz', VERSIONS=>30, TTL =>
'2592000'}


Will only one of VERSIONS and TTL be used ? If so, which?

No.

It will keep up to 30 versions.  Any version older than 2592000 will be let go.

You need to upgrade.
