Bit of progress on our end, bit of lagging as well. Our guy leading effort got little bogged down on client project to update hive/sql testbed to latest spark/sparkSQL, also launching public service so we have been bit scattered recently.
Will have some more updates probably after next week. We are planning on taking our client work around hive/spark, plus taking over the bigtop automation work to modernize and get that fit for human consumption outside or org. All our work and puppet modules will be open sourced, documented, hopefully start to rally some other folks around effort that find it useful Side note, another effort we are looking into is gradle tests/support. We have been leveraging serverspec for some basic infrastructure tests, but with bigtop switching over to gradle builds/testing setup in 0.8 we want to include support for that in our own efforts, probably some stuff that can be learned and leveraged in spark world for repeatable/tested infrastructure If anyone has any specific automation questions to your environment you can drop me a line directly.., will try to help out best I can. Else will post update to dev list once we get on top of our own product release and the bigtop work Nate -----Original Message----- From: David Rowe [mailto:davidr...@gmail.com] Sent: Thursday, October 02, 2014 4:44 PM To: Nicholas Chammas Cc: dev; Shivaram Venkataraman Subject: Re: EC2 clusters ready in launch time + 30 seconds I think this is exactly what packer is for. See e.g. http://www.packer.io/intro/getting-started/build-image.html On a related note, the current AMI for hvm systems (e.g. m3.*, r3.*) has a bad package for httpd, whcih causes ganglia not to start. For some reason I can't get access to the raw AMI to fix it.
