     [ https://issues.apache.org/jira/browse/IMPALA-5610?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tim Armstrong resolved IMPALA-5610.
-----------------------------------
    Resolution: Later

It would be useful to have a mechanism to do this but we don't have any flags to apply it to right now.

> We currently have a number of deprecated flags that have no effect, e.g. many of the llama flags. We will also be deprecating the old aggs and joins in a similar way.
> We should warn if any of these flags are set to a non-default value so that it's clearer that they did not have the intended effect.
