> HBase uses ~40MB, and with Phoenix we use ~56MB of Perm space out of 64MB by default. Every Filter and Coprocessor increases that.
> Running out of perm space triggers a stop the world full GC of the entire heap. We have seen this in misconfigured cluster. 
> Should we default to  {{-XX:PermSize=128m -XX:MaxPermSize=128m}} out of the box as a convenience for users?
