------------------------------------
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.
