How SAS VA pulls data from Hadoop hive into LASR MEMORY.

Well, you take the Hadoop data and...no, the question is too vague.

Please specify on what level you want this described, and why you ask this.

There are two major way to load data from Hadoop, depending on your set up. Either from a SAS/ACCESS interface, or by a co-located Hadoop, where LASR data is stored in a special format, spread across nodes as the corresponding LASR ones.

Hi Linus,

Thanks for your answer. I just want to know how the data will be updated in the LASR memory if it is connected to hadoop and if the records were updated. how the report will drill down when there is no hierarchy in Hadoop. Can you suggest the material to understan more on hadoop and SAS.

I would start with papers from Global Forums, and then read various parts of the documentation for LASR, VA admin and ACCESS to Hadoop.

Linus H response is good start. See: http://support.sas.com/resources/papers/proceedings16/index.html

In addition the details you are looking for can be found in the VA and LASR admin guides. Do you have access to those admin guides or is VA not currently licensed for you?
