Bruno Mahé commented on HADOOP-7596:
------------------------------------

Thank you very much for your reply.

But I am still confused.

I see 
{noformat}
+if [ -n "$HADOOP_SECURE_DN_USER" ]; then
+  DN_USER="root"
+  IDENT_USER=${HADOOP_SECURE_DN_USER}
+else
+  DN_USER="hdfs"
+  IDENT_USER=${DN_USER}
+fi
{noformat}

defined in src/packages/deb/init.d/hadoop-datanode but not in src/packages/rpm/init.d/hadoop-datanode
? (I am looking at https://github.com/apache/hadoop-common/blob/branch-0.20-security-205/src/packages/rpm/init.d/hadoop-datanode
so hopefully I am on the right branch)
I would be expecting an identical behavior in both init scripts and use DN_USER/IDENT_USER
for both cases

> For secure Hadoop 0.20.2xx cluster, datanode can only run with 32 bit jvm because Hadoop
only packages 32 bit jsvc.  The build process should download proper jsvc versions base on
the build architecture.  In addition, the shell script should be enhanced to locate hadoop
jar files in the proper location.
