Volodymyr Orlov commented on HADOOP-6767:
-----------------------------------------
Thank you Steve for your fast criticism on the merits. I have made some
investigations and I would like to suggest changes that will make the patch
more appropriate:
1) I will replace JNA with JNI. Thus, I'll make a code faster and there will be
no need in getting round ASF + LGPL problem. Windows native code will be build
only if releasing is done on Windows or with Wine. Hadoop will try to locate
dll in the same way as it does it now for libhadoop.so and will fall back to
Cygwin in case native library is not found
2) I will use Apache Commons Daemon instead of Java Service Wrapper
Also, all changes will be made against SVN_TRUNK, patch will not make changes
to current javadocs and will use spaces instead of tab.
Nevertheless I would like to leave service wrapper configuration files/code and
code that enables Hadoop to run on Windows without Cygwin in the same patch
because there is currently no way to start Hadoop daemons on Windows without
Cygwin. In case I will separate it into two patches, Hadoop users will still
need to apply both.
Meanwhile I would like to add a description of a use case which prompted us to
write the patch and a guide on how we are running Hadoop on Windows without
Cygwin:
