Ananth closed APEXMALHAR-2447. ------------------------------ > No indication from AbstractFileInputOperator when directory is empty > -------------------------------------------------------------------- > > Key: APEXMALHAR-2447 > URL: https://issues.apache.org/jira/browse/APEXMALHAR-2447 > Project: Apache Apex Malhar > Issue Type: Improvement > Reporter: Velineni Lakshmi Prasanna > Assignee: Velineni Lakshmi Prasanna > Priority: Minor > Fix For: 3.8.0 > > > AbstractFileInputOperator scans a directory for files and outputs the file > contents. However, when the directory is empty nothing is sent. A downstream > operator may want some basic information that the input directory is scanned, > so for example, it can create an output folder. Add a notification to the > operator when the directory is scanned for the first time. An implementation, > for example, can use this notification to send a control tuple with the > directory path notifying the downstream that the directory has been visited. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
