John Vines commented on ACCUMULO-343:
-------------------------------------
I'm definately all for clarifying the READMEs, it's nice to get a fresh pair of
eyes on them and finding the issues.
We do not currently have a mechanism in place for default constraints, nor do
we plan to. However, you should be able to set a system-wide constraint, either
via the site.xml file or via the same command in the example, but sans -t
<tablename>. However, I put emphasis as should as we recently stumbled across
some issues with constraints (I believe 320-325). Most of them deal with
operating at the various site/system/table levels of configuration so you may
not be seeing this behavior in 1.4. I believe the biggest problem you will have
with this in 1.4 and below is that the only way to disable a higher level
constraint (e.g. disable a site constraint for a single table) is by putting in
a new constraint for that numeration. This is because constraints are
(currently) numerated and replacing that constraint # with a blank one will
result in an error.
tldr; Yes, you can set them at the system level or in the site.xml file which
will have it belong to all tables, but you will probably have issues disabling
the constraint for a specific table.
I hope I was clear in explaining that, it is a bit late on my part. Let me know
if you need any clarification.

> When I inserted a record with a visibility label that was undefined, nothing
> happens. These are the steps I followed:
> {noformat}
> $ start the command line client.
> > createtable test
> test> insert florida george age 50 -l readable
> test> scan
> {noformat}
> Notice that there are no error messages or inserted records. Now let's define
> the visibility label and try again.
> {noformat}
> test> setauths -u root -s readable
> test> insert florida george age 50 -l readable
> test> scan
> florida george:age [readable] 50
> {noformat}
> Once the visibility is defined, the record is properly inserted.
