Subject the zombie NiFi
Date Mon, 13 Feb 2017 04:43:09 GMT
Hi all,

I am struggling in an infinite loop.  I want to install a new NiFi on the
same machine because the old NiFi was corrupted.  But even though I install
from an original file from NiFi website.  There are always same logs as
bellow.  I guess some file was locked and the new NiFi are trying to
recover from the error status.
