Hello,
I'm writing to ask if you can help me with an error I'm getting using Pig.
I'm debugging a UDF using Pig local and remotely attaching to the process from
Eclipse. After about a minute, I get a timeout error (copied at the bottom of
the email). Do you know if there's a way to increase the timeout or if there's
another issue here?
Thanks!
