Subject [jira] [Commented] (ACCUMULO-3147) Replication table should be user-controlled or live in accumulo namespace
Date Fri, 31 Oct 2014 20:00:35 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14192359#comment-14192359

Josh Elser commented on ACCUMULO-3147:
--------------------------------------

I guess you could call it similar to #3 (I wouldn't have, but w/e). But you got the idea:
instead of storing a fixed table name (presently 'replication', after your changes to change
the namespace 'accumulo.replication') in code, put that in ZooKeeper. It's now much easier
to handle this down the road if/when this changes again. I'm not proposing it for users (they
shouldn't be looking in ZK for anything anyways): it's for the developers.

> At present, it looks like the replication table is managed by/written to by the system
user, yet the table lives in the default namespace, which is where user tables live.
> This appears to violate the namespace model of segregating system tables from user tables.
> There's a few options for resolution:
> # Move the replication table into the reserved accumulo system namespace (there's some
complication with this, because the system namespace is currently static, and the replication
table may be created at any time; additionally, if users are expected to interact with this
table... and I'm not sure if they are at all, the system namespace is probably not appropriate).
> # Create an additional reserved system namespace for replication (my least preferred
option).
> # Use user credentials to manage/write to this table, rather than the system user (this
is what the tracer/trace table does, and this is my preferred solution.)
