Steve Loughran commented on HADOOP-3839:

I've seen the other places where cygwin is used (e.g file permission checks), and it does make sense -at least for the servers. I'm not so convinced it needs to be mandatory client side.

A check fror cygwin would be good...one option is just to handle that failure we see in the stack trace, and encode the knowledge that if whoami fails with error code=2 on windows, somebody probably hasn't got cygwin installed, or its path set up correctly.
hadoop should handle no cygwin on windows more gracefully

Key: HADOOP-3839
URL: https://issues.apache.org/jira/browse/HADOOP-3839
Project: Hadoop Core
Issue Type: Improvement
Environment: Windows XP, cygwin not installed
Reporter: Steve Loughran
Priority: Minor

There have been a couple of postings to hadoop core-user in which people can't get hdfs to come up on windows because whoami isnt on the path, which fails with an IOException error code 2.
To people not experienced in DOS error codes, this is a fairly meanless number which invariably leads to time wasted and support emails.
1. the error could be caught and handled by printing some better hints (point to a wiki page?)
2. is whoami really needed on DOS-based filesystems?
