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?
