Multiple tables export with Sqoop in a Oozie workflow

pvillard — Mon, 13 Jun 2016 16:56:47 GMT

Hi,

What is the best way to have an Oozie action performing a multiple tables export using Sqoop?

Context:

I have a HDFS directory containing one file per destination table but the number of files is not constant over time
The filename allows me to know what is the name of the target table

I'd like to have one single Oozie action calling Sqoop to export all the files in the target database.

Is it something we can do? What are the available options?

Ah just read that its an export. But again I don't think there is any automated way to do that.

So I suppose your only choice is to make a custom shell/ssh action that runs a script ( shell, python ... ) that lists the files from the directory and then executes sqoop jobs for them. Would be my approach.
