Subject [jira] [Created] (ACCUMULO-3091) Support user defined properties
Date Fri, 29 Aug 2014 00:11:08 GMT
Dave Marion created ACCUMULO-3091:

             Summary: Support user defined properties
                 Key: ACCUMULO-3091
             Project: Accumulo
          Issue Type: New Feature
          Components: master, tserver
            Reporter: Dave Marion

Accumulo supports user supplied application code running on the server side, but it does not
currently share the configuration space with users.

Two specific examples come to mind, but there may be others:

1. Users can supply their own tablet balancer, but have no way to configure it. I can envision
a balancer implementation that allows an administrator to modify the number of migrations
per iteration by manipulating a property.

2. Users can supply their own iterator implementations. The same iterator class can be applied
to multiple tables, each with their own configuration. The behavior of an iterator could be
modified at runtime by an administrator by manipulating one property instead of modifying
the iterator configuration on each table where it is being used.

Need to think about property visibility...
