run a java program in oozie

[Vishnu Viswanath <vi...@gmail.com>]

Hi,

Scenario:

I have a map-reduce program. I would like to schedule this program to run
every 'x' hours.

i believe this could be achieved using
${coord:hours(int n)}

But i also want to run a small java program which does some post processing
of reading the content from hdfs and put it to a relational database.

Any pointer on how this can be done?

Regards

If your directory or directories in HDFS represent tables of your
relational database, I would consider to take a loot at Sqoop.

If MR and java code are dependent and need to be scheduled in every hour, you can write one workflow with two actions : MR action and followed by a java action. At last, scheduled the WF using a hourly coordinator.

If you need more details about this, please let us know.
