MapReduce Improvements in the MapR Hadoop Distribution

Hi everyone,

Sorry for the late notice but we have scheduled the next Big Data meetup. See below for more information on the topic and the presenter. Please note that we have moved the meetup from our regular Tuesday to Thursday to accommodate the speaker. Future meetups will be on Tuesdays.  Second, please note that we have changed our venue to the new Central Library. Matthew toured the library and the new meeting room (room 302) seats 125 people and has fast internet so we are excited about the new location and all future meetups will be anticipated to be at this location.

I hope to see everyone there!

Cheers, Pitt Fagan

MapR is the only Hadoop distribution that provides full data protection, no single points of failure, improved performance, and dramatic ease of use advantages. Adam will dive into the MapR features that provide improved performance and reliability over vanilla Hadoop. Basic outline:
* Hadoop/MapReduce background
* MapRFS vs. HDFS: FileSystem HA, Direct Access NFS, Volumes, Snapshots, Mirroring
* MapReduce improvements: DirectShuffle, JT HA, ExpressLane
* Beyond MapReduce: M7, YARN, etc.

Before Amazon, he re-engineered the National Instruments LabVIEW dataflow compiler for large-scale multicore systems. Adam earned a Master of Science in Computer Science degree from Rice University, with emphasis on performance optimization in High-Performance Computing (HPC) environments.

    Fantastic. I think the mapR filesystem is great, and how hadoop already worked. I didn't realize hadoop was so broken. :)

    Hey, Pitt. I'm not necessarily trying to change anyone's mind, but I do just want to say that I prefer the BendyWorks location for several reasons. It's a great place with a nice restaurant/bar below for after-meeting meetings.

      Bendyworks is great, but there are some major positives with the library. 1) bigger, can fit more people - we're already at the limit of the bendyworks space 2) we don't have to tear up an office every meetup, 3) they have flexible room arrangements, so we can have chairs / desks / both / none. 4) This supports their efforts to turn the library into a center of the community. 4) It's right opposite ~3/4 bars anyway!

      Ah, good points! But do you have a 3rd number 4? ;)

    I agree that Bendyworks is an awesome space, but Big Data Madison has over 260 members now and the last few meetings have been full. I'm looking forward to larger meetings and the new Central Library will hopefully be a good fit for the near future.
