Answer 1

Using the PowerShell environment variable syntax ($env:VARIABLE) instead of the batch syntax (%VARIABLE%) should suffice. Note that you must use the call operator for this to work. I'd also recommend adding double quotes in case there are spaces in the path.

& "${env:HADOOP_HOME}\bin\winutils.exe" chmod 777 /tmp/hive

The need for the call operator appears to be due to PowerShell's command parser not recognizing an expression $variable\something as a path. Without the & you'd be getting an an exception

Unexpected token '\bin\winutils.exe' in expression or statement.
