[daemon] any incompatibilities between 1.0.3 and 1.0.13

Hi,

Is there any information on incompatibilities between 1.0.3 and 1.0.13?
Hadoop is still using 1.0.3 with the known group id issue, and it needs to
be upgraded to a later version. We got this information:

http://www.apache.org/dist/commons/daemon/RELEASE-NOTES.txt

But it's not clear whether 1.0.13 would be fully backward compatible (with
1.0.3) at runtime. Thanks in advance!

Regards,
Sangjin

As far as I can tell (and I'm not an expert on hadoop), the one place where
commons-daemon is used is in SecureDataNodeStarter in Hadoop HDFS code. For
example:

http://svn.apache.org/viewvc/hadoop/common/branches/branch-2/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/datanode/SecureDataNodeStarter.java?revision=1423241&view=markup

Also, in the 1.x branch I believe the platform-native binaries are being
bundled as part of the hadoop deliverable. I don't know that it is the case
in hadoop 2.x.

This is the corresponding JIRA issue filed on HDFS:
https://issues.apache.org/jira/browse/HDFS-4497

Thanks for your help!

Regards,
Sangjin

I should be compatible, although you might wish to use some of the
newly added features. If you can point me to the relevant code and
info I can help you guys with the upgrade.
