Vinayakumar B created HDFS-7098: ----------------------------------- Summary: Support polling for more data from a write-in-progress file using same DFSInputStream Key: HDFS-7098 URL: https://issues.apache.org/jira/browse/HDFS-7098 Project: Hadoop HDFS Issue Type: Improvement Reporter: Vinayakumar B Assignee: Vinayakumar B
Currently DFSInputStream can read only till the bytes written which were written by the time of Opening it for reading. But, later there can be more bytes written to same file. If client expects more data to be available, then client can poll it continuously for more data without re-opening the stream. One simple example use case for this is tailing logs files. Currently LocalFileSystem supports this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
