[jira] [Updated] (EAGLE-249) Support Postgres as hive metadata
[ https://issues.apache.org/jira/browse/EAGLE-249?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Su Ralph updated EAGLE-249:
---------------------------
Priority: Minor (was: Major)
change to minor, as we already support that.
> Support Postgres as hive metadata
> ---------------------------------
>
> Key: EAGLE-249
> URL: https://issues.apache.org/jira/browse/EAGLE-249
> Project: Eagle
> Issue Type: Bug
> Affects Versions: v0.3.0
> Reporter: Su Ralph
> Assignee: Su Ralph
> Priority: Minor
> Fix For: v0.5.0
>
>
> From Capital One case
> ////////
> It looks very interesting that Postgres has this behavior. Is Postgres your production setting for holding hive metadata?
> If that is the case, I think we need extend Eagle a little bit to support Postgres. (Hive metadata tables use upper case for both table name and column name)

> We use the following queries, let me know if any of queries can't be run directly against postgres?
> 1. to get databases
> String sql = "select name from DBS";
> 2. to get tables
> String sql_format = "select t.tbl_name from TBLS t, DBS d where t.db_id=d.db_id and d.name='%s'";
> 3. to get columns
> String sql_format =
> "select c.column_name " +
> "from DBS d join TBLS t on d.db_id=t.db_id " +
> "join SDS s on t.sd_id=s.sd_id " +
> "join COLUMNS_V2 c on s.cd_id=c.cd_id " +
