Subject [jira] [Commented] (ACCUMULO-2114) default namespace name should be part of the public api
Date Wed, 05 Feb 2014 20:00:10 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13892501#comment-13892501
] 

Christopher Tubbs commented on ACCUMULO-2114:
---------------------------------------------

Well, I was thinking that the "default" namespace could be the results of getConnector().namespaceOps().getDefaultNamespace(),
and the connector-specific default namespace would be the results of getConnector(namespace).namespaceOps().getDefaultNamespace().
But, I can see how this could be non-intuitive for users to understand the answer to the question:
"What is the *default* default namespace?". Alternatively, we could add a separate namespaceOps().getCurrentNamespace()
or something. The merits of that can be debated later if we decide to pursue that feature.

Other reasons for moving it to namespaceOps():
1. Constants are harder to find if separated into a separate file, because users don't know
to go looking there if they're working with a separate class.
2. Constants files tend to get bloated, which diminishes their value for consumers (although
they still have value for refactoring).
3. Encouraging client use of constants, with compile-time binding, means that compiled client
code could break if we change the value of the constant.

> The name of the default namespace currently lives in org.apache.accumulo.client.impl.Namespaces
which is not part of the public api. We should make this variable part of the public API to
make it easier for users to interact with namespaces.
