Subject [jira] [Commented] (ACCUMULO-2844) Remove master/slave terminology
Date Thu, 09 Apr 2015 02:19:13 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2844?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14486585#comment-14486585
] 

Christopher Tubbs commented on ACCUMULO-2844:
---------------------------------------------

I think at a minimum, we can deprecate the "slaves" file, and replace it with a "tservers"
one (updating the scripts to fall back to "slaves" if "tservers" is missing), in 1.7.0, if
somebody has the time to make that happen.

>          Issue Type: Task
>    Affects Versions: 1.5.0, 1.5.1, 1.6.0
>            Reporter: Sean Busbey
>            Assignee: Sean Busbey

> I'd like to remove our use of master/slave terminology in favor of something that doesn't
carry a racially charged meaning.
> As a side effect I'd also like to pick names that carry better meaning of how things
work within Accumulo.
> In the case of a single cluster, I'd like to
> * Change the Master role to Coordinator
> * Change the associated master server package to coordinator
> * Change the master configuration file to be named coordinators
> * Change the slaves configuration file to be named tservers
> In the case of the in-progress replication work I'd like to change terminology:
> * use _Primary Cluster_  in place of _Master Cluster_
> * use _Replica Clusters_ in place of _Slave Clusters_
> I intend to do this in all active branches in a way that maintains compatibility of existing
configuration files and serialized actions (i.e. fate operations) within their major branch.
In the current unreleased major branch I expect upgrading will require user action (e.g. renaming
configuration files).
