             Summary: ListHDFS doesn't list files from updated 'directory'
                 Key: NIFI-5000
                 URL: https://issues.apache.org/jira/browse/NIFI-5000
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
    Affects Versions: 1.5.0, 1.4.0, 1.3.0, 1.2.0
            Reporter: Sivaprasanna Sethuraman
            Assignee: Sivaprasanna Sethuraman


ListHDFS lists files and saves the latest listed files' modified time - latestTimestampListed and latestTimestampEmitted in the `StateMap`. It is overriding `onPropertyModified` to check if the `Directory` or the `File Filter` has been modified and if they are indeed modified, it will reset the statemap variables to `-1L` so as to list all the files from the updated `Directory` or according to the updated `File Filter`. However it is not working as intended.

*Scenario:*
 # Create two directories in HDFS
 ## > hdfs dfs -mkdir /test1
 ## > hdfs dfs -mkdir /test2
 # Write files to the above directories in the following order:
 ## > hdfs dfs -put sample.txt */test1/t1_1.txt* --
 ## > hdfs dfs -put sample.txt */test2/t2_1.txt*
 ## > hdfs dfs -put sample.txt */test1/t1_2.txt*
 # Configure ListHDFS and set *Directory* to */test1* and start the processor. It will produce two flowfiles: *t1_1.txt* and *t1_2.txt*
 # Stop the processor. Configure and set *Directory* to */test2*. Ideally the state variables (listed and emitted timestamp) should be reset and they should list the file *t2_1.txt* but it is not.
 # Now put one more file to test2:
 ## > hdfs dfs -put sample.txt */test2/2_2.txt*
 # This would have listed the file *t2_2.txt*. File t2_1.txt is missed

Little debugging helped me found that the `onPropertyModified` indeed works as intended but somewhere else the code still reads the last saved state i.e. the modified time of */test1/t1_2.txt*
