Matei Zaharia commented on HADOOP-4050:
---------------------------------------
You are right, calling mkdir on "." is strange, and the only reason I did it is
because JUnit does not create the test/data directory for me automatically.
Since you have a different Linux kernel from mine, this is probably why it's
failing for you and not for me. I've looked carefully through the build.xml
files for streaming, contrib and Hadoop itself, but I can't figure out where
exactly streaming gets its data directory to be mkdir'ed. Maybe it does do it
in Java after all. I will create a patch for build-contrib.xml that makes the
data directory at the same time it makes logs, etc to see if that fixes it.
