Please suggest if it is right time for me to start on Hadoop
I have around 2.5 years experience in production support, have minimal(like fresher with 6 months development experience) knowledge in java, unix and SQL.
I always have interest to move to a technical job role, I am not provided a chance to move out of support, however I got tuned to my job now. The problem is we do the same stuff everyday and feels frustrated sometimes( when even the freshers sound more knowledgeable than us in terms of technical skills)
I have the below questions in my mind regarding my career:
1) Security:: As I am working for 2+ year in same organisation, I feel my job is somewhat secure even I have average skill set. There is also onsite opportunity(some time[may be next year or after 2 years ..so on..] I will be sent to onsite in some demanding/frustrating support project if I continue to stay in same organisation.) But even after coming back I have to search for another support project only( since there will be no available time to improve skills in support projects, that too at onsite)...
If I take this path..I will have comparatively more job security(staying with same organisation for many years), financially good(due to onsite). However there will be no job satisfaction, no knowledge(no respect), no personal life,health problems due to 24*7 work
2) Change/Challenge: As a Plan B(my desired career), I want to get out of shit and switch to a fully blown technical/ data analytics related job.
If I take this Path....I will have job satisfaction, great skill-set, steady(step by step) financial growth , I believe I am also capable to learn and adapt to new technologies but have no knowledge in any technology right now..
So I have decided to continue the same job and in parallel do a self-study on any technology which has good demand (like hadoop, etc,.). so that whichever path looks fine by next year, I can take it.
Please suggest Which technology should I start with( which will have more opportunities in near future)
considering hadoop(or any data-warehousing technology) , will I get a job with no real time experience?
Hadoop will introduce you to the world of big data applications, which is likely to be a growth area for the next few years at least. So if you want to learn Hadoop, you might as well start now. It's hard work - you'll need to get used to working on a Unix/Linux machine - but there are some very helpful resources for beginners:
Intro to Hadoop and MapReduce - free online course at Udacity. Choose the "free courseware" option as you don't need the paid-for tutorial support. This is a very gentle introduction to Hadoop, using a pre-packaged virtual machine (VM) which you can download and run inside VirtualBox on a Windows PC if necessary, so you don't have to install Hadoop yourself.
Hortonworks Sandbox - Hortonworks provide their own packaged version of Hadoop with lots of extra tools integrated into it. This is a commercial product, but you can download the developer sandbox for free, which includes some excellent tutorials. The sandbox is a VM, but you access it via a web application which allows you to use all the main Hadoop tools (Pig, HBase, Hive etc) from your browser.
No more Blub for me, thank you, Vicar.
