Chris Nauroth commented on HADOOP-9500:
---------------------------------------
The problem was introduced in HADOOP-9299 with this code:
{code}
// doesn't matter what it is, but getGroups needs it set...
System.setProperty("hadoop.home.dir", "/tmp");
{code}
The logic in {{Shell}} for finding the path to winutils.exe first checks the
hadoop.home.dir property. It won't find it in /tmp, so the test fails the
first time it tries to run a winutils command.
This is easy to fix: instead of /tmp, use the HADOOP_HOME environment variable,
which is guaranteed to be configured to the correct path in
maven-surefire-plugin. I'll provide a patch shortly.
> TestUserGroupInformation#testGetServerSideGroups fails on Windows due to
> failure to find winutils.exe
