Hi,
We started to work with Avro in CDH4 and to query the Avro files using
Hive.
This does work fine for us, except for unions.
We do not understand how to query the data inside a union using Hive.
For example, let's look at the following schema:
{
"type":"record",
"name":"event",
"namespac
I think the problem is that hive is trying to import into a database named
ds12
validObjectException(
message:There is no database named ds12)
try this:
hive > create database ds12;
Also be careful you just send the entire internet your oracle PW and
username,

Here is the json-data that i load:
*
{ "blogID" : "FJY26J1333", "date" : "2012-04-01", "name" : "vpxnksu", "comment"
: "good stuff", "contact" : { "email" : "vpxn...@gmail.com", "website" :
"vpxnksu.wordpress.com" } }
{ "blogID" : "VSAUMDFGSD"
Removing last ',' in second row would make result as you expected.
I can't tell it's bug or not.
