Two theories:
1) There is junk in /tmp/hbase-${user.name} from an earlier test picked up
by the build.
2) This is something specific to the JRE version or the local environment
on hadoopqa.
I think Ted updated the precommit build config to rm -rf /tmp/hbase-* ahead
of testing.
For the second, it could be useful to dump out uname -a and java -version
ahead of running the build?
