Subject [jira] Commented: (HADOOP-6767) Patch for running Hadoop on Windows without Cygwin
Date Tue, 18 May 2010 10:05:47 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6767?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12868591#action_12868591
] 

Steve Loughran commented on HADOOP-6767:
----------------------------------------

I actually think the ASF's interpretation of the LPGL is the issue here, there's been some
coverage of the Hibernate Clause [http://www.mail-archive.com/legal-discuss@apache.org/msg00009.html]
that could get things to co-exist -someone needs to talk to the JNA people about licensing
here.

If we could get the licenses compatible then we could drop all cygwin requirements and say
"use JNA for windows". That would be a step towards making windows a supported platform, rather
than something for people to play with Hadoop on before going into production. A step: you
still need to test at real or virtual production scale with the target OS, which means some
variant of Windows Server. I don't want to get involved in that, dealing with inconsistencies
between Linuxes is painful enough. MS might be able to offer cluster time. 

First step: someone has to approach JNA and say "what do you mean by LGPL"?
