Allen Wittenauer commented on HADOOP-11464:
-------------------------------------------
bq. For the warning about single quotes, I chose to suppress it. We really want
single quotes here, because the cygpath command translates the classpath to use
the Windows-style separator, which is ;. Since this is part of a bash eval, the
semicolons would get misinterpreted as multiple bash commands. Wrapping it in
single quotes handles it correctly.
Makes sense.
bq. punt on the Tomcat stuff for now
Agreed. We'll likely need to hit this at some point though, especially since I
don't think we have a way to run these daemons on Windows at all right now.
bq. updated the comment in hadoop_os_tricks. Is this what you had in mind?
Yup!
At this point, I'm +1. I played around with the trunk version for a few hours
now, trying a few different things on my shiny new Windows VM. There are few
oddities, but these are mostly cygwin related rather than bugs in our code
AFAICT.
Awesome work! Thanks!

> The Windows compatibility work removed the dependency on Cygwin as a
> compatibility layer. However, some users may still wish to run Cygwin on a
> personal machine for running Hadoop commands that interact with a cluster.
> This issue proposes to reinstate support for launching Hadoop processes on
> Windows using Cygwin to call the bash scripts.
