Aldrin, Thanks for your response.
For GetHTTP ,I have checked to download different files even it could not run more than once. ListHDFS:I have used NiFi-1.2.0 in which configured these attributes "Hadoop Configuration Resources","Directory","RecurseSubDirectories" correctly for Hadoop-2.5.2.This runs only once not run again. *Note: *I have checked those processors in windows*.* Can you give any suggestion to solve this?
