Eric Yang commented on HADOOP-7596:
-----------------------------------
bq. Out of curiosity, what is the rationale of having a ${IDENT_USER} and
${DN_USER} ?
For secure datanode, the script should be started with root user then drop
privileges to HADOOP_SECURE_DN_USER. In the secure deployment context,
IDENT_USER=hdfs, and DN_USER=root.
bq. hdfs user is still hardcoded in several locations
For non-secure cluster, datanode process is hard coded to hdfs user.
bq. Isn't it a dangerous behaviour if a user customize this directory? (and by
mistake or knowingly set it for instance to /var/log)
chmod code was legacy code. The test log dir is to make it less destructive
while maintain backward compatibility.

> 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.
