Hello,
I hope it is ok to contact you with this question, but I did not find a forum to post it. First I'd like to say that the idea of apache drill is just great, solving the gap between "traditional" BI (mainly using SQL) and the "new" BI (hadoop, NoSQL etc). My question: I am trying to use drill via jdbc, but I have problems using the databasemeta-Interface. I am accessing a mongodb database (called HR) and a collection called EMPLOYEES (we copied Oracle's HR schema into mongo to test if our code is portable to NoSQL and other non-RDBMS-sources via Apache drill) Querying the table like "Select * from mongo.HR.EMPLOYEES" works fine, but how can I access the databasemetadata? When I try to use the method getColumns() (catalog=null, Schema = "mongo.HR", table="EMPLOYEES"), I only receive an empty resultset. I also tried to set catalog=mongo, Schema=HR, table=EMPLOYEES, but had no success? Any idea, who I could get the column metadata? Thanks a lot in advance, kind regards, Alex
