-Re: Error while exporting the data from pig latin to RDBMS
Jonathan Coveney 2012-10-17, 18:52
I have not used DBStorage myself and the comments are lacking, but there is
a syntactical issue here. All store statements have to be in the following
store relation into 'location' using storefunc(args);
So you're case needs to be
STORE data INTO 'location' using DBStorage ('com.mysql.jdbc.Driver',
127.0.0.1/AnalyticsDB','Insert into test
(created_at,host_name,auth_id) values (?,?,?)');
I'm not really sure what the significance of the "location" variable is in
this case (you can check the DBStorage code and try and glean it, or
someone else can werigh in), but that is what is going on
