How to list limited number of directories under hdfs using hdfslist processor in nifi ?

New Contributor

We have around 6k tables under Hdfs as directories and when we use hdfslist processor in nifi its listing everything and killing the cluster . How can we select limited number of tables may 100 or 200 instead of listing everything ?

To address the limited number of tables is to limit the number of files in HDFS terms, Listing strategy can only be controlled by File Filter and file-filter-mode on what can be listed.

The Listting processing has a two-step

-->What to list " controlled by the filter "

-->From Whereto list  "where in your case looks like sub directory under root has a widespread and number of nested sub dirs are huge where the processor is spending time on recursive searching.
