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?

Many Thanks,
