Brock Noland commented on FLUME-2245:
-------------------------------------
Hi,
Yes, I was able to test this the BucketWriter writer change (and only that) and
I found it fixed this issue.
Note: I used kill -STOP on the DN to reproduce.

> Project: Flume
> Issue Type: Bug
> Reporter: Juhani Connolly

> This is running on a snapshot of Flume-1.5 with the git hash
> 99db32ccd163daf9d7685f0e8485941701e1133d
> When a datanode goes unresponsive for a significant amount of time(for
> example a big gc) an append failure will occur followed by repeated time outs
> appearing in the log, and failure to close the stream. Relevant section of
> logs attached(where it first starts appearing.
> The same log repeats periodically, consistently running into a
> TimeoutException.
> Restarting flume(or presumably just the HDFSSink) solves the issue.
> Probable cause in comments
