Description

Hi 

Nifi GETHDFS processor gets stuck/hung or not able to idnentify the files in HDFS directory.

While i let the process to keep retrying multiple times with a schedule state of retry in every 0 second, the processor identifies the file after 300-400 retries.

Sharing the log information below:

Earlier this was working smooth, the issue is noticed after we restarted the  nifi restart? Could somebody help with the unexpected behaviour or issue noticed.
