[jira] [Created] (FLUME-1968) FileChannel new format

Brock Noland created FLUME-1968:
-----------------------------------

             Summary: FileChannel new format
                 Key: FLUME-1968
                 URL: https://issues.apache.org/jira/browse/FLUME-1968
             Project: Flume
          Issue Type: Bug
            Reporter: Brock Noland


There are a couple issues with the current format:

1) We have to track the offset at checkpoint time and write the offset to a special location so we can seek to that offset during replay. In FLUME-1516 we are tracking two offsets.

2) We have no way to detect partial writes FLUME-1967

3) We can only checksum the body of the event, not the entire record FLUME-1485 and therefore cannot detect corruption outside an event body.
