Date Mon, 03 Jun 2013 22:33:26 GMT
Hi Azuryy,

thanks for the update. Sorry for the silly question, but where can I download the patched
version?
If I look into the closest mirror (i.e. http://mirror.netcologne.de/apache.org/hadoop/common/),
I can see that the Hadoop 1.1.2 version was last updated on Jan. 31st.
Thanks in advance,

Matteo

PS: just to confirm that I tried a minimal Hadoop 1.2.0 setup, so without any security, and
the problem is there.
