Bruno Mahé commented on HADOOP-7596:
------------------------------------
Anyway, this is going off-topic. I just meant to replace in your patch:
{noformat}
- daemon --user hdfs ${HADOOP_PREFIX}/sbin/hadoop-daemon.sh --config
"${HADOOP_CONF_DIR}" stop datanode
+ if [ -n "$HADOOP_SECURE_DN_USER" ]; then
+ daemon ${HADOOP_PREFIX}/sbin/hadoop-daemon.sh --config
"${HADOOP_CONF_DIR}" stop datanode
+ else
+ daemon --user hdfs ${HADOOP_PREFIX}/sbin/hadoop-daemon.sh --config
"${HADOOP_CONF_DIR}" stop datanode
+ fi
{noformat}
by something similar to what you did in the debian side. Which would look like
something like:
{noformat}
+if [ -n "$HADOOP_SECURE_DN_USER" ]; then
+ DN_USER="root"
+else
+ DN_USER="hdfs"
+fi
{noformat}
And then later on:
{noformat}
- daemon --user hdfs ${HADOOP_PREFIX}/sbin/hadoop-daemon.sh --config
"${HADOOP_CONF_DIR}" stop datanode
+ daemon --user $DN_USER ${HADOOP_PREFIX}/sbin/hadoop-daemon.sh --config
"${HADOOP_CONF_DIR}" stop datanode
{noformat}
So you end up with a similar structure as the deb side and less repetition.

> Project: Hadoop Common
> Issue Type: Bug
> Components: build
> Affects Versions: 0.20.204.0
> Environment: Java 6, RedHat EL 5.6
> Reporter: Eric Yang
> Assignee: Eric Yang
> Fix For: 0.20.205.0

>
> 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.
