Subject [jira] Commented: (CHUKWA-4) Collectors don't finish writing .done datasink from last .chukwa datasink when stopped using bin/stop-collectors
Date Sun, 04 Apr 2010 18:07:27 GMT

Ari Rabkin commented on CHUKWA-4:
---------------------------------

I don't think you need to identify the bad chunk. Why not just move the "close new file and
rename things" logic into the exception handler? I would split the handler into "ChecksumException"
-- where you recover by closing and renaming the file -- and everything else, which you should
log the way you do now.

> When I use start-collectors, it creates the datasink as expected, writes to it as per
normal, i.e. writes to the .chukwa file, and roll overs work fine when it renames the .chukwa
file to .done. However, when I use bin/stop-collectors to shut down the running collector
it leaves a .chukwa file in the HDFS file system. Not sure if this is a valid sink or not,
but I think that the collector should gracefully clean up the datasink and rename it .done
before exiting.
