Using Slider as a default mechanism for HBase on HDP 2.2

Hi,

I just installed HDP 2.2 through Ambari. I was under the impression that in HDP 2.2., the default deployment mechanism for HBase/Accumulo is through Slider (i.e., they are enabled by default for YARN). However, that does not seem to be the case. Can we choose to install HBase through Slider during HDP installation through Ambari? i.e., was there a customization option that I missed?

If Slider is not the default mechanism for HBase on HDP 2.2, why not?

Thanks!
