Subject Re: Drill on Amazon?

Hi Ted!

Thank you for your notes; your timing is perfect as I just now (finally) 
have enough time to start working on this in earnest.

I have started collecting some info - there's not much on Drill per se, 
but there are what seem to be analogous efforts in using Spark and R on EMR.

While apologizing for posting links, I would appreciate any and all 
input as to whether a similar approach might work with Drill.

1.) The upshot is to use a boostrap script to install software on 
cluster startup. In another project, I had had success using R in Hadoop 
streaming (i.e., sans RHadoop) so I was thinking this might be a way to 
get the Drillbits onto the slave (core/task in AWS) nodes in the 
cluster. Then one would ssh to the master and subsequently connect to 
the core nodes.

Installing Apache Spark on an Amazon EMR Cluster

...this next entry illustrates getting RHadoop onto the core nodes:

Statistical Analysis with Open-Source R and RStudio on Amazon EMR

Does that make sense?

2.) I noticed that Amazon is now offering MapR instances in EMR; would 
there be any advantage to using one of these instead of the "stock" 
Amazon instances?

3.) While I've only been reading and not (yet) directly experimenting, 
I'm not sure I understand your note on UDP multicast. Is there a link to 
the Drill wiki or documentation where this is explained (i.e., why this 
is pertinent)?

At the risk of redundancy, here's my slightly-refined basic 
(hypothetical) plan:

i.) Create EMR instance with Drill bits installed on core/task/slave 
nodes with a bootstrap script

ii.) Load data onto S3 and create Hive external table: have data 
partitioned into "folders" (i.e., with S3 prefixes) and associate Hive 
indexes with this partitioning. This would only be used for creating the 
framework in the Hive metadata store that Drill could leverage.

iii.) Connect to the master node via SSH and then to a slave node (I 
guess via jdbc) to then query Hive ala:

Does this seem to make sense?


Again, thank you for the notes!
