Have you installed Nifi previously on the same machine? or Trying to upgrade?

Hi, I have a requirement to handle 10k files in Nifi in parallel. Whats the best way to handle this scenario? Say for example if i use GetFile Processor and point to a loading directory, will it take 10k files one by one or it will be handled in parallel. Is there any properties or way to set it up so that 10k files will be loaded in parallel. Its not necessarily GetFile. ListFile-FetchFile also will do. Another question: Does nifi creates a single JVM instance to handle all the flowfiles being generated, or will there be multiple JVM's created for different processes?

@dsun Thanks. ExecuteStreamCommand is the processor which we are going to make use of. Nifi role will be til creating a data mart from all source and oozie will take care of the rest of the flow.

Thanks
for the recommendations. Am planning to make use of Nifi for data
ingestion alone and rest of the flow using oozie.we are building a
system with similar to ETL (staging,refine layer). So there will be
multiple hive tables created and merged & resulting data will be
sent to external systems. Planning to go to Nifi (data ingestion) and
(workflow schedule) oozie. Coming to common processing logic, correct me
if am wrong. lets say PutMail will be in one separate process group and
entire flow will have a link to that group whenever failure occurs.

Am pretty new to Nifi. The soltion we have designed is using Nifi for data ingestion and oozie for scheduling. Using oozie, hive tables are loaded, merged and hive-to-hive schema copy is performed. 1) Is it possible/ recommended using Nifi to completely achieve it. 2) What are the areas that needs to be taken care while using this approach? 3) The flow after developed using Nifi has so many common processors (updateattribute,putmail etc). Is there any way to set common processors as a separate template and make use of it wherever necessary) Note: The data flow is scheduled to run once in a day.
