Hello, In my flow I need to copy HDFS files based on dynamic wildcard to another HDFS location within the same cluster. I have Process Group Variables: source_path = 'hdfs:///source/' file_prefix = 'myflow_' And a Flowfile Attribute: file_timestamp = '20190520' The source directory contains 4 files, and I need to copy the bolded two of them. The filenames to be copied are "${source_path}${file_prefix}${file_timestamp}.part*". hdfs:///source/myflow_20190412.part000 hdfs:///source/myflow_20190520.part000 hdfs:///source/myflow_20190520.part001 hdfs:///source/otherflow_20190625.part000 The MoveHDFS processor in NiFi v1.8.0 does not support Expression Language in the File Filter Regex field. How could I achieve this functionality - except for using ExecuteStreamCommand with "hdfs dfs -cp"? Thank you for your help, Piotr ... View more
