Joydeep Sen Sarma commented on HIVE-1465:
-----------------------------------------

yeah - i am a little confused by this too. for many hive variables - when i try to print them out using 'set' command - i see the unexpanded variable. yet - when hadoop uses those same variables (typically path settings) - the variable is expanded out. i am guessing we are not using the right interface call to get these variables in hive code.
