`rescue in read': end of file reached (Thrift::TransportException)

Hi there, any ideas? I am receiving this error when I want to execute a query. Am I missing anything? Maybe some authentication issue, network issue?

Thanks in advance.

```
require 'rubygems'
require 'impala'

Impala.connect('my ip', 21000) do |conn|
puts conn
puts conn.open?
puts conn.inspect
cursor = conn.query('my query') # ERROR in this line
cursor.each do |row|
puts row
end
end

```
