----------------------------------
Fix Version/s: 4.9.0
> Collect stats correct for local indexes
> ---------------------------------------

> Key: PHOENIX-3361
> URL: https://issues.apache.org/jira/browse/PHOENIX-3361
> Project: Phoenix
> Issue Type: Bug
> Reporter: James Taylor
> Fix For: 4.9.0
>
>
> Stats are not being correctly collected for local indexes and tables with
> local indexes, because the logic that deletes the old stats is based on all
> store families of a table. Thus, when stats are collected for a table with
> local indexes, the local index stats would be deleted and when the stats for
> a local index are collected, the stats for the table will be deleted.
> Instead, if we cache stats per column family instead of across entire table,
> plus detect if we're collecting stats for a local index versus the data
> table, we can fix this issue. Caching stats per column family makes more
> sense anyway, because depending on the query, we may only use the stats
> associated with the default column family. Also, we wouldn't want to have to
> pull over stats for local index with the data table stats.
