Subject Re: Spark or custom processor?

Hi,
ListenSyslog (using the approach that is being discussed currently in another thread – ListenSyslog
running on primary node as RGP, all other nodes connecting to the port that the RPG exposes).
Various enrichment, routing on attributes etc. and finally into HDFS as Avro.
I want to branch off at an appropriate point in the flow and do some further realtime analysis
– got the output to port feeding to Spark process working fine (notwithstanding the issue
that you have been so kind to help with previously with the SSLContext), just thinking about
if this is most appropriate solution.

I have dabbled with a custom processor (for enriching url splitting/ enriching etc. – probably
could have done with ExecuteScript processor in hindsight) so am comfortable with going this
route if that is deemed more appropriate.

Thanks
Conrad

Conrad,

I would think that you could do this all in NiFi.

How do the log files come into NiFi? TailFile, ListenUDP/ListenTCP, List+FetchFile?

Hi,
Any advice on ‘best’ architectural approach whereby some processing function has to be
applied to every flow file in a dataflow with some (possible) output based on flowfile content.
e.g. inspect log files for specific ip then send message to syslog

approach 1
Spark
Output port from NiFi -> Spark listens to that stream -> processes and outputs accordingly
Advantages – scale spark job on Yarn, decoupled (reusable) from NiFi
Disadvantages – adds complexity, decoupled from NiFi.

Approach 2
NiFi
Custom processor -> PutSyslog
Advantages – reuse existing NiFi processors/ capability, obvious flow (design intent)
Disadvantages – scale??

Any comments/ advice/ experience of either approaches?

Thanks
Conrad
