yeah. that works as expected. the schema drives the column list in the
select statement (not the hdfs file.)
you'd have nulls if your schema had *more* columns than the hdfs file had
fields.

Hi All-
I have struggled for awhile with a simple and straightforward driver that I
can use to connect to Hive Server 2 in a very similar manner as a mysql
driver in python. I know there are a few ways like using thrift or ODBC but
all require significant amount of installation. I decided to create
Never mind. Figured out where that was.

create *any* table at all.
Any help is appreciated.

Hi Andy,
Using Http over Thrift is currently a feature in development and has

only NOSASL authentication mode set on the server side. There is a
follow-up JIRA (https://issues.apache.org/jira/browse/HIVE-4764) which will

I found a solution.
In testing, I tried out the HTTPClientTransport that's now supported for
Thrift in Hive 0.12. This required me to set the Hive conf var
hive.server2.enable.doAs to false in order for it to work. When I reverted
back to using the BufferedTransport, with this property in my

Should I create 12500 clusters? Or should I create 100 clusters and then use
