Subject [jira] [Commented] (ACCUMULO-3147) Replication table should be user-controlled or live in accumulo namespace
Date Fri, 19 Sep 2014 13:22:34 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14140454#comment-14140454
] 

Eric Newton commented on ACCUMULO-3147:
---------------------------------------

bq. 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.)

This is a decision I have come to regret. It confuses new users when the tracer is unable
to create its table because the username/password hasn't been properly configured.  If I were
to do it again, I would not even start the tracer by default, and I would use system credentials.

> 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.)
