Subject [jira] [Commented] (ACCUMULO-3700) Table Balancer support for multi-tennacy
Date Fri, 27 Mar 2015 21:14:53 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3700?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14384681#comment-14384681

Keith Turner commented on ACCUMULO-3700:
----------------------------------------

I wonder if this could be accomplished with a balancer that wraps another balancer and limits
the set of tservers passed to the {{balancer()}} and {{getAssignment()}} methods.

> In a multi-tenant environment I would like to be able to segregate tables to subset of
tablet servers for processing isolation and maintaining SLAs.
> My thinking is this could be accomplished by defining a configuration that maps namespaces
to tablet servers and a custom balancer will utilize this configuration to balance tablets
only on the servers associated with its namespace.
