Hi Yusaku. Awesome community support! With people like you, I am sure that Ambari will be the best monitor tool!
My last question (I don't want bored you :) ) : Is true that It is not possible to use Ambari with an existing Hadoop installation? So, it is necessary to install all the platform using Ambari. This could be a problem for our platform team. Regards. 2015-03-21 1:01 GMT+00:00 Yusaku Sako <[email protected]>: > Hi Angel, > > > Ganglia is going to be replace by Ambari Metric System.
