The fact that all the data and software was ready to use on an already prepared VM, provided by the trainer in external disks.
I mostly liked the trainer giving real live Examples.
I genuinely enjoyed the big competences of Trainer.
I genuinely enjoyed the many hands-on sessions.
It was very hands-on, we spent half the time actually doing things in Clouded/Hardtop, running different commands, checking the system, and so on. The extra materials (books, websites, etc. .) were really appreciated, we will have to continue to learn. The installations were quite fun, and very handy, the cluster setup from scratch was really good.
Lot of hands-on exercises.
Ambari management tool. Ability to discuss practical Hadoop experiences from other business case than telecom.
The VM I liked very much The Teacher was very knowledgeable regarding the topic as well as other topics, he was very nice and friendly I liked the facility in Dubai.
