[jira] [Commented] (ACCUMULO-3004) Remove thrown Exceptions when Instance and/or Connector are set multiple times on InputFormat

["Josh Elser (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ACCUMULO-3004?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14065246#comment-14065246 ] 

Josh Elser commented on ACCUMULO-3004:
--------------------------------------

Additionally, this only happens on the connector and instance. You can merrily set the tableName, iterators, offline scanners, etc as many times as desired.

I imagine this was done because of the differences in how this data is serialized within the configuration (similar to ACCUMULO-3001), but there has to be something better that can be done.

>          Issue Type: Improvement
>    Affects Versions: 1.5.1, 1.6.0

>             Fix For: 1.7.0

>
> If a user happens to set the Connector for Instance information on the same Configuration object multiple times, they get slammed with an IllegalArgumentException.
> These setters should be idempotent and having them invoked with the same data multiple times should not change the serialized form in the Configuration.
> Tentatively marked for 1.7.0 as its a change in how 1.5 and 1.6 currently operate.
