Subject [jira] [Created] (HDFS-2962) jsvc needs to be removed from hdfs packaging

jsvc needs to be removed from hdfs packaging

                 Key: HDFS-2962
                 URL: https://issues.apache.org/jira/browse/HDFS-2962
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: data-node, security
    Affects Versions: 0.23.0
            Reporter: Mingjie Lai
             Fix For: 0.23.1

As we discussed at HDFS-2303:

... hit the same problem today when I started to try secured DN of 0.23. The shipped jsvc
(commons-daemon-1.0.3) with 0.23 doesn't work on my local ubuntu 11.10 (as described by atm,
with libcap.2 instead of 1), nor our cluster centos 5 (without any libcap).

The problem doesn't happen to 0.20.205 (what we use now) since commons-daemon-1.0.2 jsvc binary
doesn't link to any libcap (http://archive.apache.org/dist/commons/daemon/binaries/1.0.2/linux/commons-daemon-1.0.2-bin-linux-${os-arch}.tar.gz)

So the current way - downloading jsvc binary - won't work for 0.23+ secured DN. 

jsvc shouldn't be bundled with hadoop. Instead, it should be installed by user.
