[jira] [Created] (FLUME-1197) Use of "timestamp" Header is hardcoded and not configurable

Arvind Prabhakar created FLUME-1197:
---------------------------------------

             Summary: Use of "timestamp" Header is hardcoded and not configurable
                 Key: FLUME-1197
                 URL: https://issues.apache.org/jira/browse/FLUME-1197
             Project: Flume
          Issue Type: Improvement
            Reporter: Arvind Prabhakar


Currently the HDFS sink uses the "timestamp" header to resolve the destination file path. The Syslog sources inject this header into the events for such downstream use.

This enhancement request to change this functionality such that:
* The header name is configurable and defaults to "flume.timestamp" to reduce collision with application namespace
* The system still works with "timestamp" header to preserve backward compatibility.

[jira] [Commented] (FLUME-1197) Use of "timestamp" Header is hardcoded and not configurable

E. Sammer commented on FLUME-1197:
----------------------------------

I can see making the header configurable (although I still don't like it) but I'd prefer not to make it flume.timestamp by default. The "system provided" headers should simply be unqualified. Those that use custom headers should use their own qualified namespace.
