Hey guys,
I've done some rework on this PR. After some discussions with Alluxio
folks, it seems that there are some limitations at the moment (v1.3.0) and I've
made some modifications to take into account those limitations.
### System properties
At the moment, it seems it is not possible to initialize the Alluxio client
inside NiFi without using system properties. And in any case, multi Alluxio
clusters handling is not supported at the moment.
### Initialization
Once the client is initialized, it cannot be unchanged unless NiFi is
restarted. Even if provided IP/port are incorrect, the client initialization
will not do any check. To avoid mistakes, I've added a simple check to ensure
that something is listening at IP/port before initializing the client.
*Improvement on Alluxio's side is tracked here:
https://alluxio.atlassian.net/browse/ALLUXIO-2120*
I've updated processors description to note it as **experimental** and let
the users know what are the current limitations. Hopefully, this won't be a
show stopper to get this first version into NiFi and get feedbacks from the
community.
