Eli Collins commented on HBASE-5655:
------------------------------------
The issue is that the DRFA doesn't have the ability to cap the the #files or
space usage, so people who aren't using host-level log rotation fill up their
log partitions, their clusters crash hard. The idea here is to change the
default to something safe (won't crash your cluster) and people who want to
keep lots of logs can adjust the limit accordingly, eg they can bump up the
default to the size of their log partition. Should make HBase more
user-friendly. Given that the default is 5gb (lots of logs!) I suspect few
people will need to do that.
Ideally we'd be able to keep daily files AND limit space usage, unfortunately
the DRFA doesn't support that =(
Given that this is an incompatible change it may be better to target for 94 or
the singularity.

> The current default log4j policy is to use Daily Rolling File Appender
> (DRFA). At times, its good to have a cap on the maximum size of the logs in
> order to limit its disk usage. Here is a proposal to set a new file appemder
> (RFA) as the default appender. It can be configured via env so that existing
> tools can use the current behavior of using DRFA instead.
> This is in parallel with jira Hadoop-8149.
