Hi guys Honestly this blog platform you are using sucks (it's slow and UI is poor) try something better like https://www.discourse.org/ It's a shame given the fact contents are great Hope it will help Mario ps I found it because http://discuss.itversity.com/

hi @GabiGow as you see from https://www.cloudera.com/documentation/enterprise/release-notes/topics/cdh_vd_cdh_package_tarball.html 5.8 has 1.6 already installed not sure you need to really wait for cdh 5.10 better off starting now. Bests Mario

considering what cloudera fee charges for attempting the exam .***`We are not announcing a date for when the exam content changes. If you wish to make sure that you your exam is with the latest versions of our products, wait to schedule your exam until April. If you wish to take the exam with the old version then schedule immediately. We will be making changes as soon as we can guarantee a proper exam and without any further warning.` *** IS not great to hear ... you might think to give a second shot for who fails above 50% to make it a bit more fair in my opinion during this transition period bests M

they said changes will happen in April

Hi I 'd say N one use uservoice or something like that to up vote ideas and suggestions not as reply to this Bests mario

obar1 · ‎11-19-2016

it seems that sudo yum remove vmware-tools* and then sudo ./vmware-install.pl -d works

obar1 · ‎11-19-2016

after you click to update the vmware tools and unpack and run the you can get error about the fact you cannot update it as it was installed by pkg managements system so sudo ./vmware-install.pl will not work

obar1 · ‎11-18-2016
