How to automatically auto load HDFS tables after restart of LASR server?

Hi everyone,

As our SAS VA setup includes both the temporary LASR server and the permanent HDFS layer, I would like to ensure that whenever we (for some dubious reasons) have to restart our LASR server, then everything stored both on LASR/HDFS automatically gets reloaded from HDFS to LASR.

How is that setup - can anyone revert me and my team to a description, paper and/or cookbook on how to set this up.

I expect this to be possible - otherwise why have a HDFS layer? But I have not been able to trick the tips&trick on how to do it.

Please help :-)

Kind regards,
Jesper

The closest to "automatic way" is to write a script that runs after the SAS VA restart.  The calls a SAS program that runs the code to do the job.

The SAS LASR Analytics Server manual discusses several coding methods for working with the LASR and HDFS. Then it's just a matter of writing some server scripts and testing your process.
