Todd Lipcon commented on HDFS-1594:
-----------------------------------
Dhruba: I haven't dug into it yet, but I've also seen this before when the
drive hosting the log4j logs fills up. I think there are some cases in which we
do a System.exit(1) which can corrupt the logs -- the issue being that, even
though we fsync after every edit, there's no guarantee that we don't get half
of the preceding edit. Hairong's proposal to checksum each edit should help
here.
