Booked in Cloudera’s Hadoop Administrator Certification Exam

I booked in the certification exam for Cloudera’s Hadoop Administrator to be done this Tuesday morning at 10AM. Cloudera recently changed the way the exam is conducted. Students used to need to go to a specific exam centre and sit inside a classroom for the test, but now it is all done online through a partner called Innovative Exams.


The way it works is to install a chrome extension from Innovative Exams, and allow them to watch you, both your face and desktop monitors remotely, via web cam and the chrome extension. They will catch you if you try to cheat. It is very convenience since you don’t have to physically go to another place for the test, but it does feel a bit odd when someone is watching all your movements for the whole one and half hours.

Anyway, I have studied hard and now ready for the exam. Wow, the very first exam since I graduated from Uni almost 10 years ago. Fingers crossed.

During my first week, I have been spending most of my time reading and learning all the required knowledge, including Hadoop, Hive, Spark, Sqoop, ZooKeeper, Impala, HCatalog, Avro, Parquet, Sentry & Oozie.

As you can see, there are a hell lot of study I have to do and also Cloudera will be sending me over to the US for further training for about 3-4 weeks. And there will be 3 certificate exams that I have to sit on and pass in order for me to continue working here at Cloudera. So there is some pressure here to push my study.

So far I have enjoyed all those learnings and I hope I can become a Hadoop expert in no time.

Looking forward to start taking new cases in the next 2-3 months.

Another Redundancy & Waiting For New Job Comfirmation

On 16th of December, about two weeks ago, Betfair suddenly announced around 40 job redundancies across the whole business, both in Melbourne and Hobart. That morning after the announcement, I could sense the chaos atmosphere, I could feel that everyone was nervous, but I wasn’t, because I have come through the same deal before and it all turned out to be not toooo bad for me.

Here is a bit of background. Betfair AU was owned by both Crown and Betfair UK up until August this year, and then Crown bought full Betfair AU’s share from Betfair UK. Just one day before the announcement, Crown acquired another betting company called BetEasy. As part of company restructure, all Betfair’s sportsbook products will be merged with BetEasy, hence any duplicated departments will be made redundant.


Here is a bit of reading you can have on The Australian.

I had the meeting with my boss around 11:40AM. I only worked in Betfair for just a bit over 3 months, and I thought the maximum I could get should be around 2-4 weeks, However, when they presented redundancy package to me, which covered around 3 months of my salary, I was in full surprise, as you would expect! On top of that, even though we finished on that day, Betfair would pay us until 24th of December (the final day). And also for those who would like to apply for vacancies through Crown, Betfair & BetEasy, the final pay day will be extended to 12th of January in 2015.

I am now in talks with BetEasy to see whether any opportunities for redeployment back to BetEasy, and I also have some other opportunities with other companies whose decision can be finalised by mid January.

Now I am just totally relaxing with family (but still very busy taking care of kids and pregnant wife) at home and waiting for our third baby to come by the end of January. Wish me luck that I can start my new job in February after spending sometime helping with the new born baby.

Fingers Crossed!

Migrate VPS to InterServer

My old VPS was with HostMist, which I have been with for quite a few years, the plan was US$6 for 10GB space and 128MB memory. I actually got around 1GB for quite a while, and I think it was their fault that they accidentally gave me extra RAM, :).

Recently my memory has been reverted to 128MB and I can feel that the server can not cope with basic LAMP setup anymore, as MySQL just kept crashing and site is down most of the time.

I guess it is time to do a bit of research and see whether there are  other cheaper alternatives or similar ones with more RAM. After about 2 days of Googling, I landed with InterServer with a trial. This is what it offers:



Price is the same but with more storage and memory. I signed up straightaway and got Ubuntu 13.04 installed in no time. However, while I was installing LAMP, I kept getting “Out of Memory” errors by simply running “apt-get install” commands.

I wasn’t happy but not sure why a small Ubuntu Server can’t handle 512MB of memory, according to Official Ubuntu website:



512MB is more than enough, with only LAMP installed. I emailed billing department and ask them to give me a refund as the server simply can’t do anything.

I got a reply in a couple of hours and they agree to give me free extra 512MB or they can give me full refund. 1GB of RAM? Why not give it a try? So here it is, my server is now running quite stable for the last couple of days,  and I have switched the DNS on Godaddy for all my domains to the new server.

Let’s see what happens with 1GB memory on VPS and how long it will last, for a server hosts about 4 blogs with small traffic.

Weekly Goal – Cycling 200KM By Friday

I have lots of friends who do close, or more than 200KMs of cycling each week. I have been riding to working for more than 1 year now, but only limited to one way each day of 22KMs, so averaging to around 100KMs/week.

I would like to push myself a bit harder this week. So I have setup a goal in RunKeeper to ride at least 200KM by this Friday, which means I will simply need to cycle both ways to and from work each day.

I have also check the weather and it turned out it will be sunny until next week, so it is a good week to choose.
