Utility to tail the contents of a directory -------------------------------------------
Key: HADOOP-6338 URL: https://issues.apache.org/jira/browse/HADOOP-6338 Project: Hadoop Common Issue Type: Improvement Reporter: dhruba borthakur Assignee: dhruba borthakur There is an existing utility "bin/hadoop fs -tail -f <filename>" that prints the last few records from the specified file. A map-reduce application uses a directory as a data-set and it creates multiple files in a HDFS directory. I am proposing that we extend "bin/hadoop fs -tail -f <directory>" to tail the contents of a directory. The files in the directory can be sorted (lexicographically, or based on modtimes) to arrive at the virtual sequence of the set of files inside the directory. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
