------------------------------
Summary: 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
Fix For: v0.4.0
>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)
Thanks

So what I found is the following:
http://stackoverflow.com/questions/6331504/omitting-the-double-quote-to-do-query-on-postgresql
I modified the queries to have quotes like so (but it still does not seem like
it is working correctly, I am investigating further):
1. select ’NAME' from "DBS";
2. select 't.TBL_NAME' from "TBLS" t, "DBS" d where 't.db_id'='d.db_id' and
'd.name'='%s’;
3. 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'
where 'd.name'='%s' and 't.tbl_name'='%s’;

Subject: Re: Fail to get WEB_CONFIG configurations for data classification
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 " +
"where d.name='%s' and t.tbl_name='%s';";
