`rescue in read': end of file reached (Thrift::TransportException) #24

Open paulocheque opened 7 years ago

paulocheque commented 7 years ago

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

Hi Paulo,

Were you able to figure out this problem?

I am getting similar kind of error - What does end of file reached means?
