Aldrin Piri commented on NIFI-259:
----------------------------------
Performed some additional testing starting up a Kerberos server according to a
few different guides out there on CentOS 7 in a VM and working with a clustered
instance of NiFi. Followed the steps in the Administrator guide and managed to
get things running. Verified not being able to access the specified root
without the appropriate credentials getting an 'Authentication is not valid'
error without.
Overall, with the additional efforts provided on the branch, things look good.
+1 and will merge into master.
> Framework should offer Processors/extensions a way to manage simple state

> It is not uncommon for processors to need managed state which persists
> across restarts. One good example of this is the GetHTTP processor which
> needs to save state of the last cache/e-tag information it received from the
> server it interacts with so that it can avoid constantly pulling an unchanged
> resource.
> Rather than making processors roll their own persistant state management
> perhaps we can offer something to them via the ProcessContext which will
> allow them to save simple primitive values and limited length Strings which
> are local to that node and which are local to that processor only.
