Allen Wittenauer commented on HADOOP-11464:
-------------------------------------------
I'm still working on getting an environment to test this, but a few things pop
out:
* I suspect that java.library.path/JAVA_LIBRARY_PATH needs to get mangled in
hadoop_finalize_libpaths for Windows as well.
* shellcheck is throwing four new warnings:
{code}
In ./hadoop-common-project/hadoop-common/src/main/bin/hadoop-functions.sh line
667:
eval $1='`cygpath -p -w "${!1}" 2>/dev/null`'
^-- SC2086: Double quote to prevent globbing and word splitting.
^-- SC2016: Expressions don't expand in single quotes, use double
quotes for that.

(I really need to get the shell test bits written up...)
* To support the tomcat bits (kms and eventually httpfs), the
hadoop_finalize_catalina_opts function is going to need some work. Of course,
we can always punt on that till later.
* We should probably change the comment in hadoop_os_tricks tricks now.
* Because yarn is (or at least was) idiotic, it adds some custom stuff to
HADOOP_OPTS in bin/yarn that probably need to be looked over. Of course, if
someone says we don't need them anymore, I'd much rather they go away.

> 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.
