Very High quality instruction on the fundmentals of Hadoop. I had very little knowledge of this technology, and can not afford the high priced courses. Thank you again.
@Lynn : Now, I am a fan of yours . Please upload some more videos with more concepts involved. Keep On adding more information in this era. Nice job Done thru such an informative and clear presentation Thank Q in advance. Regards BABA
Hey, nice tutorial... but i did not get one thing,, at about 24:25 you say they should have a gray square and the name node. Is this gray square some other name node than the one shown as a blue box , or were referring to the secondary name node ?
This was very helpful. I am organizing a short course on Big Data at the college where I teach. It's oriented more towards a business major to understand some general concepts, but I was hoping to work through some hands-on examples. Thanks for producing this!
Thanks for sharing these great videos Lynn. The clarity was great. I have a question. My background is more in statistical analysis and modeling. I am mostly familiar with SAS and R but not Java or C++. However, I would really like to build my career on hadoop and big data in the future. What are some books, advise you can recommend for me. Thank you.
You will probably want to focus more on learning a higher level query language - like Hive, Impala (for Cloudera) and/or Mahout, rather than the nitty-gritty of MapReduce programming. There is also a library, called RHadoop, that you can try. I have only tested this in POC, not in production, so I can't really say how well it performs.
Lynn, You are a great presenter of materials! I would have preferred to have seen examples in your presentation. Also, your presentation is a bit fast-paced for people like me....
Hi Lynn thanks for these great videos. I have a question. So one of the core premise of Hadoop HDFS is to bring computation to data but not the other way around. My question is - In real world when a company decides to use Hadoop, do they first transfer all their data into node (HDFS) clusters? So the data is coming to nodes even though only for the first time I guess. Is my understanding correct?
Glad you are enjoying these videos. The data can be processed from many sources. For on premise installations, the most common source(s) are the HDFS data nodes. However, many Hadoop implementations run in the cloud - for example if using AWS, then customers may use S3 rather than EC2 (compute) + EBS (storage - which would be formatted as HDFS)
Sanjay Das Glad you like this - Here is a simple sample (Word Count) from Cloudera - www.cloudera.com/content/cloudera/en/documentation/HadoopTutorial/CDH4/Hadoop-Tutorial/ht_usage.html
Hey Lynn, Thanks for the series of hadoop lectures they are just amazing! Can you please help me with a project or a proof of concept some thing like that. Thanks
I am an engineer passed out this year. I will be attending Goldman Sachs interview for big data job. So I wanted to do a project to show my knowledge. I hopefully crack it by watching your lectures :)
***** I got selected by IBM, I did not attend the interview that time. But Goldman work culture is admired in IT, once you have Goldman's experience, other companies offer you high salary and people leave.
***** I am not into development, I am into infrastructure. I am currently working in India, yes I can see that IBM India is getting many projects and opportunities.
Hi Lynn Whenever I try to create the Cloudera using the OracleVM virtualbox, I repeatedly get the error "Failed to open a session for the virtual machine ClouderaTest" and the virtual machine gets terminated. Any solution that you might suggest? Thanks again.
Can anybody tell me where to obtain a copy of the Java code used in this presentation? All the clues I followed lead to dead ends. It is not on the earliest version of CDH4 still available. It may be on an earlier version that Cloudera took down. Does anybody know?
Hi Lady Lynn, Your videos are too much useful to learn the Hadoop. But one issue I am getting... Not able to install cloudera-quickstart-vm-5.4.0-0-vmware.vmwarevm . Please guide me. I have also gone through stackoverflow.com/questions/29310712/how-to-fix-vmware-fusion-to-import-existing-machine-cloudera-grayed-out and this post is not useful. Please help me
Sanjay Das were you able to to try this with a 64-bit machine? www.cloudera.com/content/cloudera/en/documentation/core/v5-2-x/topics/cloudera_quickstart_vm.html
Very High quality instruction on the fundmentals of Hadoop. I had very little knowledge of this technology, and can not afford the high priced courses. Thank you again.
This is a wonderful introduction to Hadoop MapReduce - I look forward to watching the rest. Thank you so much!
Nicely done! I started my job carrer with hadoop , now involved in storm kafka, zookeeper and other advanced big data technologies
Hi Lynn, this training materials are really good. you did excellent job.
Amazing! This is probably the best youtube channel for Hadoop/MapR!
Thank You!
Great series. Offers great insight and accessibility for Hadoop as a beginner. You are a true hero for making these :D Keep it up!
thanks for your kind words #KeepLearning
Very good teaching technique. I am happy to attend your video.
Thanks
Lynn Langit great job here! I've learned so much from this presentation! Thanks!!
Thanks Lyn you have done a wonderful job, got a very good idea.
Thanks alot madam for these videos. #Respect :) and i started subscribing you in youtube
This was a great tutorial. I have and will continue to learn alot from you. Thank you so much.
awesome!!! keen to see you back.

Excellent! This is a very useful guide!
Thanks Lynn for sharing the very useful and important points. How about the openings on Hadoop?
really glad you enjoyed it, I plan to make more later this year as well
Thank you thank you thank you for these great tutorials!
Just logged in to thanks for this great intro!
Really Nice Tutorial. Thanks for posting
Really Good Tutorial . Thanks for Sharing
Very nice, thanks for sharing...
Thanks for the tutorial - very intuitive.
glad to hear it was helpful, I plan to make more videos on this topic area later this year
Thanks for sharing your knowledge...

Lynn Langit Thank you very much for the suggestions. I would really help me.
awesome , its pretty informative
Awesome
Lang it, Bobby!
Thanks for this video.
Lynn,
You are a great presenter of materials! I would have preferred to have seen examples in your presentation. Also, your presentation is a bit fast-paced for people like me....
Furthermore, is Hadoop used to chart the demand for Hadoop?
thanks so much, glad you enjoyed it

highly thankful to you
Glad to hear it! I am working some new Hadoop content for publication later this year too! #keepLearning
Thanks for such a helpful series of hadoop lectures. Would you mind sending me a sample project where hadoop is implemented please?
Sanjay Das Glad you like this - Here is a simple sample (Word Count) from Cloudera - www.cloudera.com/content/cloudera/en/documentation/HadoopTutorial/CDH4/Hadoop-Tutorial/ht_usage.html

Thanks again
very useful!Thanks!
glad you are finding this useful
Great! thank you so much!
Hey Lynn,
Thanks for the series of hadoop lectures they are just amazing! Can you please help me with a project or a proof of concept some thing like that.
Thanks
I am glad that you found this tutorial useful. I am not available for contract work (due to current bookings) until mid Jan 2015.

What's you review on JP Morgan?

Hi Lynn,
Now the Cloudera not able to open on VMWare. So need your help.
+Sanjay Das
Before using cloudera vmware make sure that you have enabled virtualization in your machine
Hi Vinayak, thanks for ur Support. It is solved
i'm learning hadoop
