Subject [jira] [Commented] (ACCUMULO-3147) Replication table should be user-controlled or live in accumulo namespace
Date Fri, 19 Sep 2014 19:22:34 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14141128#comment-14141128
] 

Christopher Tubbs commented on ACCUMULO-3147:
---------------------------------------------

There was a ticket to allow tables to be created in an offline state (ACCUMULO-1904) in the
API. To support that, some modifications need to be made on the server-side for creating table.
Upgrade/init don't use the same code path as the API create tables, but I think some of it
is shared (the adding of entries in ZK).

> 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.)
