SAS LASR In Hadoop.

[vula]

Hi Techies,

Can any one let me know how the lasr server is co located in Hadoop environment. 

My req is : I do have a lot of data located in different countries in the form of legacy and relational databases, so the team will ingest all the files and data into hadoop environment. So from there the data should be strucured in hive table format. Now we have to do all transformations using SAS DI or EG and load into LASR in memory to consume it for VA reports as per the requirement.

So i need to understand

1.how the data will be colocated  in Hadoop.

2. Where the calculations for all these tranformations will happen.

3. How to load the updated records from hadoop environment to LASR memory.

Any body can you please explain all the possible scenarios or the documentation that explain with architectural diagrams.

Thanks..

Hi @vula

1.how the data will be colocated  in Hadoop.
The 9 FAQs about SAS VA paper may be able to answer some of your questions.  Here's the video of the talk.

2. Where the calculations for all these tranformations will happen.

It can be a mixture of some being in the SAS DI/EG and some in SAS VA - depending on what makes sense for the report.  You don't want all of your calculations in your dataset.

3. How to load the updated records from hadoop environment to LASR memory.
There are multiple methods - those are discussed in the paper above. 

You should also read the LASR Admin manual for more specific guidance.
