Daniel Templeton commented on HDFS-9782:
----------------------------------------
The granularity of the directory names is 1 minute, but that doesn't require
that the interval have a 1-minute granularity. I was thinking of the case of a
90-second interval. If you think that has the potential to create confusion, I
can drop seconds from the allowed units.
> RollingFileSystemSink should have configurable roll interval

> Right now it defaults to rolling at the top of every hour. Instead that
> interval should be configurable. The interval should also allow for some
> play so that all hosts don't try to flush their files simultaneously.
> I'm filing this in HDFS because I suspect it will involve touching the HDFS
> tests. If it turns out not to, I'll move it into common instead.
