Bill Havanki commented on ACCUMULO-2228:
----------------------------------------
I'm running on Hadoop 2.0.0-cdh4.5.0. HDFS-4404 was committed after 2.0.0, but
the CDH release happens to include a backport for it \[1]. I think in my
particular case that what I'm seeing was actually fixed under HADOOP-9792 - see
my last comment on ACCUMULO-2227 for details - and that was also fixed after
2.0.0, but is wasn't backported into what I'm using.
So your hypothesis that I'm using an outdated Hadoop is correct! :) But now I'm
not sure whether it's worth working around it.
